| 主权项 | 1. A method of selecting an algorithm for channel estimation in a communication system, the method comprising: calculating a parameter indicative of an accuracy of a channel estimation algorithm, the parameter being calculated based on a summation of square differences of channel estimates at different times normalized by an estimated received power, the estimate of the received power being determined after channel estimation, the summation being over a number of transmit antennas, a number of receive antennas, and a number of subcarriers; and selecting between a first channel estimation algorithm and a second channel estimation algorithm based on the parameter. | ||
