Abstract:
1. An apparatus including a single-input-multiple-output/multiple-input-single-output (SIMO/MISO) transceiver for providing packet data communication with a single-input-single-output (SISO) transceiver, comprising: a plurality of signal terminals for conveying a plurality of incoming radio frequency (RF) signals received via at least a portion of a plurality of spatially diverse antenna elements and corresponding to a wireless data signal originating from a particular SISO RF transceiver, and for conveying a plurality of outgoing RF signals to be transmitted via at least another portion of said plurality of spatially diverse antenna elements for reception by said particular SISO RF transceiver; receiver circuitry coupled to at least a portion of said plurality of signal terminals and responsive to said plurality of incoming RF signals by providing a corresponding plurality of incoming data signals; channel estimation circuitry coupled to said receiver circuitry and responsive to said plurality of incoming data signals by providing a plurality of receiver channel gain coefficients, wherein each one of said plurality of receiver channel gain coefficients corresponds to a relative signal strength of a respective one of said plurality of incoming RF signals; channel profile circuitry coupled to said channel estimation circuitry and responsive to said plurality of receiver channel gain coefficients by providing a related plurality of transmitter channel gain coefficients, wherein each one of said plurality of transmitter channel gain coefficients corresponds to a normalized inverse of a respective one of said plurality of receiver channel gain coefficients; scaling circuitry coupled to said channel profile circuitry and responsive to said plurality of transmitter channel gain coefficients by scaling one or more outgoing data signals to provide a plurality of related digital data signals; and transmitter circuitry coupled to said scaling circuitry and at least another portion of said plurality of signal terminals, and responsive to said plurality of related digital data signals by providing said plurality of outgoing RF signals.
