Abstract: A processor (216) time-shares correlators (206) to process (402) pilot channels for a plurality of branches to derive pilot symbols for each of the plurality of branches before processing control and data channels. The processor and the correlators cooperate to determine (404) from the pilot symbols a timing estimate for each of the plurality of branches. A signal quality estimator (210) determines (406) from the pilot symbols a signal quality for each of the plurality of branches. Subsequently, the processor cooperates with the correlators to process (408) the control and data channels of the plurality of branches, in an order determined by a plurality of branch attributes including at least one of the signal quality and the timing estimate determined for each of the plurality of branches.

Abstract: A code-division-multiple-access (CDMA) system employing spread-spectrum modulation. The CDMA system has a base station (BS), and a plurality of subscriber units. The signals transmitted between the base station and subscriber unit use spread-spectrum modulation. The improvement method for adaptive reverse power control (APC) from a subscriber unit (SU) to a base station (BS), comprises the steps of sending from the subscriber unit, using spread-spectrum modulation, a SU-spreading code on a reverse channel. The base station despreads the SU-spreading code on the reverse channel as a despread signal, determines a first power level Pd which includes power of the despread signal plus noise and a second power level PN, which includes despread-noise power. The base station determines a first error signal e1, from the first power level Pd, the second power level PN, and a required signal-to-noise ratio SNRREQ for service type, and a second error signal e2, from a measure of total received power Prt at the base station, and an automatic gain control (AGC) set point Po. The base station forms a combined error signal from the first error signal e1, the second error signal e2, a first weight a1, and a second weight a2, and hard limits the combined error signal to form a single APC bit. The APC bit is transmitted to the subscriber unit. In response to the APC bit, the subscriber adjusts transmitter power to the base station.

Abstract: A subscriber unit for controlling transmission power during the establishment of a communication channel utilizes the transmission of a short code during initial power ramp-up. The short code is a sequence which has a much shorter period than a conventional access code. The ramp-up starts from an initial power level which is quickly increased, while repeatedly transmitting the short code until a detection signal is received by the base station. The use of short codes limits power overshoot and interference.

Abstract: An adaptive radio receiver utilizes control functions derived from received signals in an interference-limited environment to decide whether to implement conventional single-user demodulation or joint demodulation. The decision to implement joint or conventional demodulation is based upon the values of estimates derived for Doppler spread, carrier-to-interference plus noise, dispersiveness and the likelihood of the presence of a dominant interferer.

Abstract: A spread spectrum system having an assignor, a spread-spectrum processor and a transmitter. The assignor assigns each arriving information signal to a message-code signal. Each message-code signal is different then other message-code signals. The spread-spectrum processor generates a pilot code signal and processes the information signals with the message-code signals to generate spread-spectrum process-message signals synchronized to the pilot-code signal. A transmitter combines the spread-spectrum process-message signals and the pilot-code signal to generate a CDM signal. The transmitter modulates the CDM signal with a carrier signal for transmission over the communications channel.

Abstract: In an exemplary communication system, a multiplicity of mobile terminals are to share a communication link with a host processor communicating through base transceivers. The mobile terminals evaluate communication signals being transmitted to one or more of the mobile transceivers and according to the evaluation of such signals, each mobile terminal independently selects a relatively high data rate or a lower more conservative data rate for communication with the host processor. The mobile terminal enters a dormant state after a fixed period elapses during which the mobile unit is not engaged in communication with the base station. Periodically, the mobile terminal reenters active state in receive mode for a brief interval and if no polling signal or other message directed to the mobile terminal is present, the mobile terminal returns to dormant state. When a signal is directed to the mobile terminal, the mobile terminal remains in active receive mode until a fixed period after a communication session is completed and then returns to dormant/active cycling. A base station utilizing a dormant polling protocol transmits polling sequences to a plurality of remote transceivers during periods of heavy loading. During periods of low loading, the base station stops polling and enters into a dormant state, listening for communication request from the remote transceivers. Upon receiving such a request, the base station immediately responds by servicing the requesting remote transceiver. In this way, the base station provides optimized utilization of the communication channel during periods of heavy and light loading conditions.

Abstract: A spread-spectrum system having an assignor, a spread-spectrum processor, a call processor, and an information-channel-mode modifier. The assignor assigns each information signal arriving at the spread-spectrum system to a message-code signal. Each of the message-code signals supports a pre-determined information-channel rate. Several information signals have different channel rates, and each information signal is assigned according to the required channel rate. The spread-spectrum processor generates a pilot-code signal, and spread-spectrum processes the information signals with the message-code signals to generate a plurality of spread-spectrum processed-message signals, respectively. The message-code signals are synchronized to the pilot-code signal. The call processor provides a call-type signal corresponding to the information signal rate for the several information signals having several different channel rates. In response to the call-type signal, the information-channel-mode modifier changes a combination of the information signals and the message-code signals to support the several different channel rates for the several information signals having several different channel rates.
