Channel Equalization for OFDM Systems in Noisy Channel Using RLS

In this paper, we present channel equalization technique for orthogonal frequency division multiplexing (OFDM) systems in noisy channel using RLS. The proposed technique has a good performance in noisy channel. It improves the communication quality. We have compared the performances of the presented technique by measuring bit error rate with 16-QAM, 32-QAM and 64-QAM as modulation schemes.
