Patent ID: 7254196

Claim:
In a receiver of a multiple-input multiple-output (MIMO) system, the receiver having a plurality of receiver antennas, a method comprising: (a) receiving signals from a plurality of transmitter antennas, each transmitter antenna transmitting multiple channels; (b) for each of a plurality of channels originating from the transmit antennas, estimating a CIR value characterizing channel impulse response (CIR) of the channel; (c) summing the CIR values for the plurality of channels to generate a plurality of summed CIR values; (d) integrating the summed CIR values over a specified window to generate an integrated summed CIR value; (e) determining symbol timing in the received signals based on the integrated summed CIR value; and (f) processing the received signals based on the determined symbol timing, wherein: a plurality of integrated summed CIR values are generated corresponding to a plurality of different instances of the specified window, each instance corresponding to integrating a different set of summed CIR values for the plurality of channels; and the determined symbol timing is based on selecting a maximum integrated summed CIR value of the plurality of integrated summed CIR values.
