In this work, we evaluate the performance of Wavelet-Coding into offering robustness for OFDM signals against the combined effects of varying fading and noise bursts. Wavelet-Code enables high diversity gains with a low complex receiver, and, most notably, without compromising the system’s spectral efficiency. The results show that the Wavelet-Coded OFDM system achieves a BER of 10−3 with nearly 6 dB less SNR than the convolutional coded OFDM system in frequency selective channels with a normalized channel response variation rate of ζ = 10−4.The proposed system fits as a key enabler for the use of mm-wave frequencies in future generation mobile communication due to its robustness against multipath fading.
