摘要：
A blind channel estimation scheme for OFDM is proposed. The algorithm is based on the ML-principle and features a very fast convergence rate. No reference symbols are needed to resolve the phase ambiguity. Simulations show the performance in mobile environments at high Doppler frequencies and short to medium delay spreads. The proposed approach maximizes the spectral efficiency by avoiding any reference symbols or pilots, and it minimizes the BER by using a non-differential modulation scheme.
