ABSTRACT:
Systems and methods for processing received signals are disclosed and may include determining, for each block of data in a received frame, diversity combining weight vectors based on a channel estimate and a correlation matrix of an unwanted signal. For each sample in each of the block of data in the received frame, a corresponding one of the diversity combining weight vectors may be applied to extract a corresponding logic level. For the each block of the data in the received frame, a new correlation matrix of the unwanted signal may be generated based on the extracted corresponding logic level and the channel estimate, to process the received frame. The received signals may include a sequence of information data blocks, and each data block may include a plurality of samples. Each of the received signals may include an orthogonal frequency division multiplexing (OFDM) symbol and/or a multicarrier modulated symbol.
