摘要： In an example embodiment, a time of arrival circuit coupled to a wireless transceiver configured to determine a time of arrival of a wireless signal. The time of arrival circuit is operative to perform a coarse-scale frequency domain correlation of the actual samples with a predetermined ideal sample. The time of arrival circuit determines a maximum coarse correlation coefficient. The time delay circuit is operative to determine a plurality of fine correlation coefficients by interpolating around the peak coarse correlation coefficient. The time of arrival circuit determines a maximum correlation coefficient from the plurality of fine correlation coefficients and a time delay associated with the maximum correlation coefficient, the time of arrival is based on the time delay associated with the maximum correlation coefficient.

摘要： Multiple-input multiple-output (MIMO) wireless communication techniques are provided that involve mapping multiple spatial streams to corresponding modes of a wireless channel between a plurality of antennas of a first wireless communication device and a plurality of antennas of a second wireless communication device so as to allocate or distribute power unequally to the plurality of modes. In addition, techniques are provided herein to cyclically shift a mapping of spatial streams to modes of the channel.
