FPGA implementation of modified leaky least mean square channel estimation algorithm

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.
