Abstract
Generalized Frequency Division Multiplexing (GFD-M) is a promising candidate waveform for the air interface of the fifth generation (5G) communication networks. The combination of GFDM and time-reversal space-time coding (TR-STC) can improve the bit error rate (BER) performance. In this paper, we employ Walsh-Hadamard Transform (WHT) in TR-STC-GFDM systems to further enhance the system performance over frequency-selective time-variant channels. Simulation results show that with slight increase in complexity, WHT can substantially reduce the BER of the STC-GFDM systems. Meanwhile, the peak-to-average power ratio (PAPR) of the system is also reduced.
