| Abstract: | Based on the wireless measure and control communication system of high speed trains, selective diversity combining over multipath channels is researched in this paper. Four SNR estimators are simulated over additive white Gaussian noise channels (AWGN) and multipath channels. The application of Equalization improves the performance of the estimation over the multipath channels. The result of the simulation verifies the validity of this method. |
