Performance Analysis of Polar Coded OFDM with Different Frequency Offsets and Code Rates

Abstract

For Orthogonal Frequency Division Multiplexing (OFDM), new challenges are arising everyday in Channel Coding. In this paper, for the improvement of bit error rate performance of OFDM, Polar Code is utilized. Successive Cancellation decoding is used at the receiver. Performance of OFDM system with various frequency offsets for different code rates is compared based on bit error rate. The results show that bit error rate changes with variation in frequency offsets. As code rate increases performance of bit error rate degrades and vice versa.
