Abstract :
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.
