Impulsive noise mitigation in Haar DWT based OFDM systems

Impulsive noise mitigation in Haar DWT based OFDM systems

In this work, a simple mitigation technique for the effect of impulsive noise in Haar discrete wavelet transform (DWT) based OFDM systems is presented. Based on the analysis for a certain configuration of Haar DWT-OFDM, redundancy in the transmitted samples was found and exploited to mitigate th...
