| Abstract: | As to the severe multi-path's fading problem in troposcatter communication,it studied channels' fast and slow fading characteristics and introduced orthogonal frequency division multiplexing(OFDM) to the communication,which had the characteristic of combating fading in multi-path channels.It established the system model based on OFDM and studied error performances in different channel estimation algorithms contrastively,including LS,LMMSE and transform domain algorithm based on DFT.It also simulated error p... |
