Abstract:
The present disclosure includes techniques to process signals in a communication system, in which multiple signal processing units process signals received from multiple antennae. The signal processor units are controlled by operational-mode control signals, which are generated using an estimated Carrier-to-Interference-Noise-Ratio (CINR). The estimated CINR is generated using an equalized and combined signal, which is generated from the received signals and the estimated channel responses using the processed signals according to an operational mode. In another embodiment, a controller generates sub-carrier allocation signals using an allocation base. A channel status information (CSI) and multiple-input-multiple-output (MIMO) controller generates sub-carrier CSI signals and operational-mode control signals using the sub-carrier allocation signals, estimated channel responses, and estimated CINR. The operational-mode control signals select one of multiple antenna paths. A transmitter-diversity processor generates transmitter-diversity signals as a function of at least a mapped signal, sub-carrier CSI signals, and operational mode control signals.
