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(More)
In this paper, we propose a modified time-domain channel estimation algorithm for OFDM systems working under impulsive noise conditions. The proposed method employs two time-domain windows to reduce additive white Gaussian noise and impulsive noise components included in the estimated channel impulse response (CIR). Meanwhile, the impulse noise equalizer(More)
