Abstract :
Channel estimation is a technique used to reduce channel inference in multipath data transmission. This paper analyses and implemented a suggested new method for channel estimation in MIMO-OFDM system. The proposed modified leaky least mean square channel estimation algorithm (M-LLMS) improves channel estimation accuracy in noisy environment. We compare the results of the proposed method with LMS, RLS and VLLMS channel estimators for SNR (1-35) and over 10,000 itertions. The computational complexities and the Bit Error Rate (BER) are reduced by the proposed algorithm.
