The receiver includes an adaptive array that has at least two antennas. Each antenna receives a signal and produces a received signal. The transmitter includes at least two transmission channels for communicating the signal from the transmitter to the receiver. The wireless communication system suppresses interference at the receiver by applying an interference suppression technique when combining the received signals. The selection of a channel at the transmitter is based on the channel performance at the receiver for each transmission channel.

摘要： A single chip wireless transceiver operable to perform voice, data and radio frequency (RF) processing is provided. This processing may be divided between various processing modules. This single chip includes a processing module having an ARM microprocessor and a digital signal processor (DSP), an RF section, and an interface module. The processing module converts an outbound voice signal into an outbound voice symbol stream, converts an inbound voice symbol stream into an inbound voice signal, converts outbound data into an outbound data symbol stream, and converts an inbound data symbol stream into inbound data. These functions may be divided between the ARM microprocessor and DSP, where the DSP supports physically layer type applications and the ARM microprocessor supports higher layer applications. Further bifurcation may be based on voice applications, data applications, and/or RF control. The RF section converts an inbound RF voice signal into the inbound voice symbol stream, converts the outbound voice symbol stream into an outbound RF voice signal, converts an inbound RF data signal into the inbound data symbol stream, and converts the outbound data symbol stream into an outbound RF data signal. The interface module provides coupling between the processing module, the RF section, and with off-chip circuits.

摘要： A wireless terminal is operable to receive a Wideband Code Division Multiple Access (WCDMA) signal from a base station and includes clock circuitry, a wireless interface, and a Primary Synchronization (PSYNC) module. The clock circuitry generates a wireless terminal clock using a wireless terminal oscillator. The wireless interface receives the WCDMA signal, which is produced by the base station using a base station clock that is produced using a base station oscillator that is more accurate than the wireless terminal oscillator. The PSYNC module includes a plurality of PSYNC correlation branches. Each PSYNC correlation branch phase rotates the WCDMA signal based upon a respective frequency offset, correlates the phase rotated WCDMA signal with a Primary Synchronization Channel (PSCH) code over a plurality of sampling positions, and produces PSYNC correlation energies based upon the correlations for each of the plurality of sampling positions.

摘要： An on-chip baseband-to-RF interface includes a receive/transmit section, a control section, and a clock section. The receive/transmit section, when in a receive mode, provides the stream of inbound symbols from the RF circuit to the baseband processing module and, when in a transmit mode, provides the stream of outbound symbols from the baseband processing module to the RF circuit. The control section provides a control communication path between the baseband processing module and the RF circuit. The clock section provides a clock communication path between the baseband processing module and the RF circuit.
