Abstract :
In this paper, the differential space-time block coding (DSTBC) technology combined with orthogonal frequency division multiplexing (OFDM) is studied in Frequency Selective Fading Channels. The influence on this system of number of subcarriers, number of paths and max Doppler frequency is analyzed. Simulation results show that the performance of the system will be improved as the number of subcarriers or multipaths increase. It is concluded that DSTBC-OFDM system is well tailored for high-mobility environment.
