摘要： The present invention is directed to the selective provision of interference canceled signal streams to demodulating fingers in a communication receiver. According to the present invention, potential interferer signal paths are identified. Signal streams having one or more potential interferer signals removed or canceled are created, and a correlation is performed to determine whether the strength of a desired signal path increased as a result. If the correlation indicates that the strength of a desired signal path was increased by the signal cancellation, the interference canceled signal stream is provided to the demodulation finger assigned to track the desired signal path. If the correlation determines that the strength of the desired signal path did not increase as a result of performing interference cancellation, the raw or a different interference canceled signal stream is provided to the demodulation finger.

摘要： Performing concurrent data communication and voice call monitoring using a single cellular radio. According to some embodiments, the UE may perform data communication, via the radio, using a first RAT, supported by a first SIM. The UE may also perform paging functions for a voice communication, via the radio, using a second RAT, supported by a second SIM. In some scenarios, the first and second RATs are the same. The data communication and the paging functions may be performed concurrently using shared physical layer resources. For example, the shared physical layer resources may comprise a shared software defined radio (SDR) configured to demodulate and/or decode signals of the data communication and the paging function. As another example, the shared physical layer resources may comprise a shared Rake receiver configured to demodulate signals of the data communication and the paging function.

摘要： Certain aspects of a method and system for achieving space and time diversity gain are disclosed. Aspects of one method may include modifying a generalization code of at least one pilot channel, to measure signal strengths for each of a plurality of received multipath signals. A portion of the plurality of received multipath signals may be combined based on the measured signal strengths. The signal strengths of the plurality of received multipath signals may be measured on a primary pilot channel by assigning its generalization code to zero. The signal strengths of the plurality of received multipath signals on a secondary pilot channel may measured by assigning its generalization code to a non-zero value.

摘要： A method for equalizing a received radio signal in a WCDMA system, comprises receiving (210), in a radio receiver, of a digital radio signal spread by scrambling codes. A channel estimation is performed (230) on the received digital radio signal for a plurality of channels. The received digital radio signal is in an equalizer equalized (240) into an equalized digital radio signal. This equalizing is performed by combining a plurality of part signals, deduced from the digital radio signal, with a respective delay and a respective combining weight. The equalizing (240) comprises provision of the combining weights based on a signal impairment matrix having elements compensated for systematic colouring caused by said scrambling codes.
