Estimation scheme for parameters of wireless channel model in OFDM communication systems

Show other versions (1)

The conventional channel estimator in OFDM system was designed to cope with the worst-case channel condi-tion,thus performance degradation can be induced due to the imperfect channel estimation.Though wiener filter based on the minimum mean-squared error（MMSE） is the optimal linear estimator,it requ...
