Transmission antennas determination method for multiple input multiple output orthogonal frequency-division multiplexing system, involves determining transmission antennas as common hypothesis by transmission antennas

摘要

The method involves placing a training sequence at a transmitter and a receiver, and evaluating the training sequence at the receiver. Transmission antennas are determined by evaluating the training sequence at the receiver. Channel impulse response for a hypothesis by the transmission antennas is estimated. A metric for the hypothesis is calculated. The transmission antennas are determined as a common hypothesis by the transmission antennas, where the metric is maximum and is provided for an incorrect hypothesis by the transmission antennas to provide a constant value.
