Performance of Modulation Diversity with Polar Encoding in Rayleigh Fading Channel

Abstract

This paper presents preliminary results concerning the use of modulation diversity combined with polar codes considering the transmission over Rayleigh fading channel. The main idea is to improve the performance of the communication system by adding diversity in a conventional polar coding scheme. Simulations results show that the proposed system outperforms the original one for all code lengths. For instance, gains of 8 dB in terms of the signal-to-noise ratio can be obtained with the proposed system considering a code length of N=1024 and a bit error probability of 10^-3.
