Abstract
In this paper, we analyze the effects of frequency offset to Weighted fractional Fourier transform (WFRFT) system under the time frequency fading channel. The expression of signal-to-interference ratio (SIR) due to ICI and ISI is derived for the first time. The bit error rate (BER) performance of BPSK modulation scheme of single-carrier (SC), OFDM and WFRFT-OFDM systems are simulated respectively. Simulation results show that when carrier offset exists, WFRFT system has superiority over both SC and OFDM systems by choosing an optimal fractional order.
