SER analysis of the MRC-OFDM receiver with pulse blanking over frequency selective fading channel

Abstract

Pulse blanking is a widely used method to eliminate impulsive interference in an orthogonal frequency division multiplexing (OFDM) receiver. To analyze the effect of the inter-carrier interference caused by pulse blanking on the symbol error rate (SER) performance of OFDM employing maximum ratio combining (MRC) receiver, the analytical expression of the signal-to-interference-noise ratio (SINR) of the OFDM employing MRC receiver is derived. Based on the SINR expression, furthermore, the SER performances over both Rayleigh and Ricean fading channels are also analyzed quantitatively. Simulation results validate the correctness of the derived formulas.

The Capacity Performance of OFDM Systems with Nonlinear Pulse Blanking in Frequency Selective Fading Channels

“…Assuming the location where the impulse noise occurs in each OFDM symbol is perfectly obtained by the impulse estimator, the ideal blanking scheme can be used to mitigate the impulse interference [30]. The n-th diagonal element of the nonlinear pulse blanking matrix is presented as follows:…”

“…Amirshahi [29] further extended this result to the coded OFDM system. Liu [30] investigated the symbol error probability of an OFDM system with ideal pulse blanking over the frequency-selective fading channel, and this result was further extended to an OFDM system with peak value blanking in [31]. In addition, Zhang et al [32] investigated the symbol error ratio performance of an OFDM system in the hidden semi-Markov impulse channel.…”
