Abstract: A variable rate communication incorporating coherent signal processing and combining is described. Within the receive system (100, 102 and 106), vectors of in-phase and quadrature-phase Walsh correlator output values (W(i)I and W(i)Q) are generated for each Rake finger over each Walsh symbol period. In-phase and quadrature-phase reference values (R(i)I and R(i)Q) are generated for each of the Rake fingers by combining the in-phase and quadrature-phase correlator outputs of the most likely Walsh symbols over a series of Walsh symbol periods. The most likely Walsh symbols are determined on a symbol-by-symbol basis by summing the Walsh correlator output energies from each finger and selecting the largest. The vectors of in-phase and quadrature-phase values are then projected (116) on the in-phase and quadrature-phase reference values and weighted by the reference amplitude. The vectors of projected and weighted values are summed via coherently combining (118), and the corresponding values from the other Rake fingers used to obtain a resultant vector of coherently demodulated Walsh correlator outputs (120). The coherently demodulated Walsh correlator outputs are used to form soft decisions (134, 136) that are deinterleaved and soft-decision Viterbi decoded.

Abstract: A method for determining the position of a mobile station (820) within a cellular telephone system having a plurality of base stations (810). A signal is transmitted at a low power level from the mobile station (820). The strength of the signal is then temporarily increased from the low power level to an increased power level, and the signal is temporarily transmitted from the mobile station (820) at this increased power level. While the signal is being temporarily transmitted from the mobile station (830) at the increased power level, the signal is used to make at least a first positional measurement. The position of the mobile station (830) is determined in accordance with the first positional measurement.

Abstract: A novel and improved method and apparatus for generating a constant data rate channel supporting signaling data transmission in an adjustable rate wireless communication system is described. In accordance with one aspect of the invention, the rate at which the channel operates may be adjusted based on the particular use and environmental conditions such that the appropriate data rate up to a maximum capability can be achieved. User data is then placed into frames (70-76) based on the selected rate. When available, signaling data is added into each frame in a predetermined amount. The resulting frame is encoded (36), repeated (38) and punctured (40) based on the selected rate and whether signaling data has been introduced, and transmitted via RF signals to the receive system.

Abstract: In a communications network, a remote unit (125) communicates with another user (30) via at least one base station (B1A). The network has a plurality of base stations (B1A-B1E) controlled by a mobile switching center (MSC-I). Each base station of the plurality of base stations (B1A-B1E) transmits an identifying pilot signal. Defining an area in which communication between a set of the base stations and the remote unit (125) is forbidden, an auxiliary antenna (130) transmits a silent region identifying pilot signal. The remote unit (125) measures a signal strength of a set of identifying pilot signals corresponding to a neighbor set of base stations (B2A-B2E) and measures a signal strength of the silent region identifying pilot signal. The remote unit (125) sends a pilot strength measurement report to the mobile switching center (MSC-I) via a first base station (B1A) with which the remote unit (125) has established communication. A handoff of the established communication between the remote unit (125) and the first base station (B1A) is initiated if the pilot strength measurement report comprises an entry corresponding to the silent region identifying pilot signal.

A transmitter (56) of the communications device (10) is configured to transmit signal power substantially continuously at a full rate power level irrespective of the variable data rate at which the transmitter (56) would otherwise be operative. In a first embodiment, a variable rate vocoder (16) within the transmitter is directed to perform full-rate vocoding, irrespective of an instantaneous level of user speech. In a second embodiment, a microprocessor (18) builds full-rate frames using repeated versions of code symbols generated by the vocoder (16). In a third embodiment, the microprocessor (18) builds full rate frames by generating signaling bits of a predetermined pattern to pad otherwise non-full frames.

Abstract: A frequency tracking loop for a communication system using orthogonal Walsh modulation is provided. The frequency tracking loop includes a correlator (120) such as a fast Hadamard transformation device, and a discriminator (130). The correlator (120) produces a correlation vector (122) representing the result of correlating the input signal with each of a set of Walsh functions, with corresponding index values. The discriminator (130) produces a frequency error signal (ê) based on the correlator (120) output with the highest energy level and other correlator outputs whose indices are related to the index of highest energy correlator output by powers of two. The frequency error signal (ê) is generated by producing a cross product between the highest energy output and one or more of the other related correlator outputs. In further aspects, a filter (140) can be used to further shape the resulting error signal (ê) and form a frequency offset estimate signal (f).
