Research on the Application of DPSK Technology in OFDM Doppler Receiver

Abstract:

A Doppler diversity receiver for OFDM is proposed by Kim B C[1], which requires channel estimation at the receiver, so its structure is complicated, what’s more, the receiver needs a large amount of calculation. Different from it, we use the differential phase modulation technology in the OFDM Doppler receiver, so the receiver can recover the original data without channel estimation, and the implement is simple, the computational complexity is low. However, experiment results show that the BER of the new receiver is higher than the conventional, and it can not get performance gains by diversity either.
