Modified orthogonal matching pursuit based ISDB-T channel estimation over fractional delay channel

Integrated Service Digital Broadcasting for Terrestrial (ISDB-T) is a Japanese standard for digital television that uses a multi-subcarrier systems called Orthogonal Frequency Division Multiplexing (OFDM). A solution for compressed sensing called Modified Orthogonal Matching Pursuit (MOMP) is capable of reducing the computational cost for channel estimation. This paper extends the capability of MOMP in fractional multipath delay channel. The simulation results shows that the proposed method is robust against fractional delay by obtaining a good Bit-Error-Rate Performance in rayleigh fading channel.
