Abstract: In a communications network, a remote unit communicates with another user via at least one base station. The network has a plurality of base stations controlled by a mobile switching center. Each base station of the plurality of base stations transmits an identifying pilot signal. To defining an area in which communication between a set of the base stations and the remote unit is forbidden, an auxiliary antenna transmits a silent region identifying pilot signal. The remote unit measures a signal strength of a set of identifying pilot signals corresponding to a neighbor set of base stations and measures a signal strength of the silent region identifying pilot signal. The remote unit sends a pilot strength measurement report to the mobile switching center via a first base station with which the remote unit has established communication. A handoff of the established communication between the remote unit and the first base station is initiated if the pilot strength measurement report comprises an entry corresponding to the silent region identifying pilot signal.

Abstract: The present invention is a method and apparatus for integrating a personal communication system with a cable television plant. A set of radio antenna devices (RAD) are connected to the cable plant. The RADs provide frequency conversion and power control of signal received from the cable plant for wireless transmission to the remote units. The RADs also provide power control and frequency conversion of wireless signals received from the remote units for transmission by the RADs onto the cable plant. In addition to the functions of standard base stations and centralized controller, the CATV base station must also compensate for gain variations in the cable plant. The downstream power control is regulated by a RAD reference signal which can be hidden within the CDMA signal for maximum efficiency. The upstream power control is regulated by an upstream gain reference signal which is individually transmitted by each RAD on the upstream link. The architecture of the present invention lends itself to a great deal of flexibility. Each RAD can operate as either an element of a distributed antenna or a base station sector unto itself. The function of each RAD as distributed antenna or as sector can be remotely programmed from the headend processor. Thus the capacity density of the system can be changed to accommodate the changing traffic density. The flexibility also is important at system deployment. When the system is deploy, the entire system may feed only one sector at the base station thus reducing the start-up cost of implementing a system. As system traffic increases, more resources can simply be added at the headend to provide more capacity.

Abstract: A method and apparatus for time division duplex (TDD) repeating a spread spectrum signal, where spread spectrum signal is comprised of a series of code symbol modulated with a pseudonoise (PN) sequence. The TDD repeater receives intermittently the spread spectrum signal at a location remote from a source supplying the spread spectrum signal. The TDD repeater amplifies and delays the received spread spectrum signal by a predetermined amount. The TDD repeater transmits intermittently the delayed amplified received spread spectrum signal such that the TDD is not receiving the spread spectrum signal when it is transmitting the signal energy.

Abstract: The invention provides a system and method for testing signal transmission quality within a digital communication system and may be incorporated within a digital cellular communication system in which information is exchanged over spread spectrum communication channels. A test sequence of digital data transmitted over the communication channel is received at a receiving station, within which is also generated a replica of the test sequence of digital data. The accuracy of transmission over the communication channel is then determined by comparing the replica of the test sequence of digital data to the test sequence of data received over the communication channel. The invention allows the test sequence of digital data to be transmitted at one of a set of known data rates, with the received station being disposed to identify the data rate associated with each test sequence of digital data. In order to simulate the transmission of, for example, voice data, the system may be configured such that each test sequence of digital data is generated in accordance with a pseudorandom process.

Abstract: A method and apparatus for matching the location of the forward link handoff boundary to the reverse link handoff boundary. A system constant is chosen which defines the product of the received power and the transmitted pilot power at every base station. The reverse link power level is measured at the base station and the forward link power level is compensated for the reverse link loading to maintain the constant product. Thereby the forward link handoff boundary to the reverse link handoff boundary are aligned to the same location.

Abstract: An apparatus and method for adding and removing a target base station from a network of base stations, which includes base stations adjacent the target base station. The apparatus is comprised of two attenuators: a first for setting an artificial receive noise power level and a second for setting a transmit level. The transmit level determines the forward link coverage area of the base station. The artificial noise level sets the reverse link coverage area of the base station. When a base station is added, initially the transmit power is low and the artificial receive noise power is high such that the forward and reverse link coverage areas are collocated in close proximity to the base station. As the base station blossoms into full operation, the artificial receive noise power is decreased and the transmit level is increased such that the two coverage areas of the base station remain balanced as the coverage areas expand. When a base station is to be removed from a system, the same attenuators are used to wilt the two coverage areas in unison as the power level transmitted from the base station decreases.

Abstract: An method and apparatus for computing a scalar projection of a vector onto another vector. The apparatus comprises a multiplying circuit and a summing circuit. The multiplying circuit is for multiplying a value representative of a first component of a first vector with a value representative of a first component of a second vector to provide a first intermediate value, and for multiplying a value representative of a second component of a first vector with a value representative of a second component of a second vector to provide a second intermediate value. The summing circuit sums the first and second intermediate values to provide a resultant value representative of the scalar projection of the first vector onto the second vector. The apparatus may further comprise a storing circuit and a selection circuit. The storing circuit is for storing the values representative of the first and second components of the first vector, and the values representative of the first and second components of the second vector. The selection circuit provides an ordered supply of these values to the multiplying circuit.
