Abstract

Abstract:

Pulse blanking based on the peak value threshold is a widely used method to eliminate impulsive interference in the orthogonal frequency division multiplexing (OFDM) receiver. To assess the impact of pulse blanking on the link transmission reliability of the OFDM receiver, the analytical expression for the signal-to-noise ratio (SNR) of the OFDM receiver with pulse blanking based on the peak value threshold is derived in the frequency selective fading channel. According to this analysis, the calculation method for symbol error probability is given in this paper. Computer simulation indicates that theory accords with simulation and validates the accuracy of theoretical analysis.

Key words: orthogonal frequency division multiplexing(OFDM), pulse blanking, peak value threshold, out SNR, symbol error probability
