Abstract

In order to deal with fast fading channel intersymbol interference,based on the analysis of the traditional space-time block coding(STBC) and researched in the decoding way to solve fast fading channel intersymbol interference problem,a new linear STBC method applied to the fast fading channel environment is derived.This method can overcome the intersymbol interference which exists in the traditional STBC.The simulations show that the new STBC method can improve the system performance compared with the traditional STBC.This improvement will become obvious with the increasing of Doppler frequency shift and SNR.The simulations indicate the validity of the method.The algorithm of the new STBC method is simple,and easy to implement.
