Abstract: To reduce the power consumption of a remote unit in a dispatch system the remote unit enters a dormant state. A base station (32) transmits a forward link broadcast signal and monitors a common access channel. A first remote unit (10) continually receives and decodes the forward link broadcast signal and determines whether said forward link broadcast signal comprises active signals (106). If the remote unit determines that the forward link broadcast signal comprises no active signals for some a duration T1, the first remote unit enters a dormant mode (148). In the dormant mode the remote unit sporadically receives and decodes said forward link broadcast signal. If this remote unit or any other remote unit on the same net presses a push to talk button (128, 130), it transmits a message on the common access channel. In response, every remote unit on the net which is in a dormant state exits the dormant state and continually monitors the forward link broadcast signal.

Abstract: In a dispatch system, power of the forward link broadcast channel transmitted from a base station is controlled such that the power level is the minimum necessary and such that transmission of the forward link broadcast channel is terminated if no remote unit (10) is located within the coverage area of the base station (32). In addition to transmitting a forward link broadcast signal, the base station monitors an access channel. A first remote unit (10) in the base station coverage area receives and decodes the forward link broadcast signal. The first remote unit (10) determines a signal quality of said forward link broadcast signal. If the signal quality is unacceptable, the remote unit transmits a power request access message. The base station responds to the request by increasing the transmission power of forward link broadcast channel (70). If no requests are received at the base station, the forward link broadcast channel is slowly decreased to a minimum (54). Transmission of the forward link broadcast channel may be terminated completely (58).

Abstract: A method and apparatus for selecting a communication system in accordance with the geographic region in which the subscriber station is located. Upon successful acquisition, the subscriber station examines the received system identification information to determine its geographical region. The subscriber station then determines whether the acquired system is the most desirable system for use in the geographical region. If it is the most desirable system for use in the geographical region, the subscriber station provides service using the acquired system. If it is not the most desirable system for use in the geographical region, the subscriber station attempts to acquire a more desirable system.

Abstract: Method and apparatus for providing centralized power control in a communication system, in which each base station (14, 16, 18, 20) in the system operates to control both the forward link and the reverse link power. A radio link manager (22) provides a common threshold for determining the proper power level of the reverse link signal at each base station (14, 16, 18, 20). The radio link manager (22) also provides a ratio of the forward link signal strength to a pilot signal strength to control forward link power control. The radio link manager (22) provides the threshold and ratio uniformly to all base stations (14, 16, 18, 20) to provide a uniform operating point for all base stations (14, 16, 18, 20) in the system, thus, increasing capacity. The same centralized power control is easily expanded to provide a mechanism for intersystem soft handoff.

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) (50A-50I) are connected to the cable plant (4). The RADs (50A-50I) provide frequency conversion and power control of signal received from the cable plant for wireless transmission to the remote units (24A-24C). The RADs (50A-50I) also provide power control and frequency conversion of wireless signals received from the remote units for transmission by the RADs (50A-50I) onto the cable plant (4). 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 (4). The downstream power control is regulated by a RAD (50A-50I) reference signal which can be hidden within the CDMA signal for maximum efficiency.

Abstract: A diversity antenna system in a mobile unit which provides time, space and antenna pattern diversity to mitigate the effects of fading at a CDMA mobile unit. The system is comprised of a diversity antenna (105) and a main antenna (100). The main antenna (100) and diversity antenna (105) are physically separated and oriented such that they have different antenna gain patterns. In a first embodiment, the diversity antenna (105) functions as a receive antenna only, while the main antenna (100) performs both transmit and receive functions. In a second embodiment, both the main antenna (100) and the diversity antenna (105) transmit and receive signals. A delay circuit (130) couples the diversity antenna (105) to a summer (135) which sums the signals received by the main antenna (100) and the diversity antenna (105), respectively.

Abstract: An amplifier circuit (40) for providing an amplified signal in response to an input signal. The amplifier circuit (40) includes an input network (44) for applying the input signal to a selected at least one of a plurality of amplifier stages. An output network (48) is provided for coupling the amplified signal from the selected at least one amplifier stage. The appropriate amplifier stage is selected by a control circuit (56) in response to a desired power value of the amplified signal. By selectively activating only the amplifier stage(s) that are necessary to provide the desired level of output power, increased DC efficiency can be accomplished in applications that require an amplifier which operates linearly over a wide dynamic range.

Abstract: A system for substantially eliminating nonlinear distortion, such as intermodulation products, introduced when a signal is processed by a nonlinear device (106). The system adds an out-of-band signal (111) to an input signal (101) to produce a combined signal (105) having a power that substantially equals a nominal operating point power for a nonlinear device (106). Preferably, the instantaneous power of the out-of-band signal (111) is adjusted by an automatic gain amplifier (120). The combined signal (105) is input to the nonlinear device (106) to produce an output. A filter (108) processes the output of the nonlinear device (106) to recover the information content of the original signal (101) after processing by the nonlinear device (106). For example, if the nonlinear device (106) is a power amplifier, the filtered output (109) is an amplification of the input signal (101).
