Abstract: A baseband processing module for use within a Radio Frequency (RF) transceiver includes a downlink/uplink interface, TX processing components, a processor, memory, RX processing components, and a turbo decoding module. The RX processing components receive a baseband RX signal from the RF front end, produce a set of IR samples from the baseband RX signal, and transfer the set of IR samples to the memory. The turbo decoding module receives at least one set of IR samples from the memory, forms a turbo code word from the at least one set of IR samples, turbo decodes the turbo code word to produce inbound data, and outputs the inbound data to the downlink/uplink interface. The turbo decoding module performs metric normalization based upon a chosen metric, performs de-rate matching, performs error detection operations, and extracts information from a MAC packet that it produces.

Abstract: A multipath wireless communication is processed to recover a transmitted data signal without performing a direct matrix inversion (DMI). First, the multipath wireless communication is received. Then HHH and HHH values associated with the multipath wireless communication are determined. Weights based on HHH and HHH associated with the received data signal may then be determined and used to recover the transmitted data signal from the received multipath wireless communication.

Abstract: The present invention provides a method of quantifying a signal to noise ratio (SNR) gap between diversity combining schemes that are operable to process multi-path wireless communications for an arbitrary number of diversity branches. The method determines the gap in a without the need to determine or know the SNR for each individual diversity combining scheme. This involves determining the number of diversity branches associated with the multi-path wireless communication and the receiver used to process the multi-path wireless communication. The SNR gap may then be expressed as the term 10log10L!/L where L is the number of diversity branches.
