METHOD AND DEVICE FOR RECEIVING DIVERSITY COMBINING IN OFDM SYSTEM

摘要

A method and device for receiving diversity combining in orthogonal frequency division multiplexing system and an orthogonal frequency division multiplexing system, wherein the method for receiving diversity combining comprises the steps as follows: comparing the signal-to-noise ratio of all the diversity branches with a threshold; if there is a diversity branch whose signal-to-noise ratio is less than the threshold, setting the channel response estimated value of one or more diversity branches to zero according to the comparison result; calculating the maximum ratio combining output according to the receiving symbol of the carrier wave and the channel response estimated value of the diversity branch.
