Abstract

This paper presents a coded decision-directed channel estimation method with two-dimensional averaging for T-DMB receivers. The proposed channel estimator produces channel coefficients robust to Doppler spread and noise, making it possible for high-performance coherent DQPSK demodulation. Simulation results show that the proposed method has better performance than the conventional method, especially at high speed-moving receivers.
