关于ofdm的信道估计方法研究的相关期刊论文，有慢衰落和快衰落信道下的研究。-Papers related to research on ofdm channel estimation method, there is a slow fading and fast fading channel under study.

举例来说在慢瑞利衰落信道中使用一根发射天线n根接收天线发送信号通过n个不同的路径-For example, in a slow Rayleigh fading channel, a transmitting antenna is used to transmit signals through the N root receiving antenna via n different paths
