Patent ID: 7486751

Claim:
A multi input multi output (MIMO) receiver for receiving signals comprising: a synchronization (SYNC) module operative to receive a plurality of received baseband signals including orthogonal frequency division multiplexing (OFDM) modulated signals and time domain complementary code keying (CCK) modulated signals, said SYNC module being operative to align the OFDM modulated signals, in time domain, to generate aligned OFDM signals and further operative to generate maximum ratio combining (MRC) parameters said MIMO receiver for processing said plurality of aligned OFDM signals to generate a plurality of subcarriers; a time domain CCK MRC module responsive to said MRC parameters for processing said CCK modulated signals in time domain to generate aligned signals, said aligned signals being combined to generate an adjusted signal for demodulation; and a frequency domain OFDM MRC module responsive to said plurality of subcarriers for combining the same in the frequency domain to generate an equalized response for demodulation, wherein said MIMO receiver for processing said CCK modulated signals in the time domain and said OFDM modulated signals in the frequency domain to improve reception of said plurality of received baseband signals by selecting the best channel conditions among the received baseband signals by combining the OFDM modulated signals on the basis of each subcarrier using varying MRC parameters optimized for each subcarrier.
