Improved Frame Structure For SC-FDE

Single Carrier Frequency Domain Equalization can improve system performance in the case of increasing system overhead.We investigate the frame structure of SC-FDE and propose an improved frame structure.The proposed frame structure divides the UW of the traditional frame into several sub-UWs and the data maintain constant.Thus,the channel estimation is accomplished by the several sub-UWs.Therefore,the accuracy of channel estimation can be improved efficiently by taking the average value of several channel estimations.Simulation results show that the proposed improved frame is superior to the traditional frame in performance of BER,meanwhile without increasing the system overhead.
