Simulation Analysis of OFDM System Demodulation Algorithm Based on Hierarchical Decision Feedback

Abstract: According to the problem that the channel is very sensitive to intersymbol interference of multipath propagation and decline feature for orthogonal frequency division multiplexing(OFDM) system on the receiver, which seriously affects the quality of communication. A hierarchical decision feedback equalization algorithm is proposed based on the analysis of spatial diversity and frequency diversity. The algorithm based on subcarrier and each antenna signal is detected by hierarchical frequency domain equalization… Show more
