<P>PROBLEM TO BE SOLVED: To provide a technique for performing channel and noise estimation for MIMO transmission sent from multiple transmission antennas to multiple reception antennas. <P>SOLUTION: Samples are obtained from the reception antennas. For a first scheme, channel estimates are derived by correlating the samples with at least one pilot sequence, and signal, noise and interference statistics are also estimated based on the samples. For a second scheme, total received energy as well as signal and interference energy is estimated based on the samples. Noise is then estimated based on the estimated total received energy and the estimated signal and interference energy. For a third scheme, signal and on-time interference statistics are estimated based on the samples. Noise and multipath interference statistics are also estimated based on the samples. Signal, noise and interference statistics are then estimated. <P>COPYRIGHT: (C)2012,JPO&INPIT |
