摘要：
Orthogonal frequency-division multiplexing (OFDM) systems are used to improve communication quality and capacity. This paper proposes using backpropagation neural networks (BPNNs) for channel estimation and equalization for OFDM systems. Simulation results show that the BER performance of the BPNN technique is better than other considered technique.
