Abstract:
A technique for performing channel and noise estimation for a MIMO transmission sent from multiple transmit antennas to multiple receive antennas is described. Samples are obtained from multiple receive antennas for a multiple-input multiple-output (MIMO) transmission sent from multiple transmit antennas. Channel estimates are derived by correlating the samples with at least one pilot sequence. Signal, noise and interference statistics are also estimated based on a cross product of the samples. Equalizer weights are derived. The correlating includes multiplying a sample vector for a chip period and a complex conjugated pilot chip for the chip period offset by a delay.
