Abstract :
This paper proposed an oversampling Modified Orthogonal Matching Pursuit based channel estimation for ISDB-T in fractional delay TU6 channel. The simulation shows that the proposed method has better bit-error-rate performance compared to the conventional method. In addition, the oversampling MOMP requires only less computational cost to improved the performance in fractional delay.
