Abstract EN
Compressive sensing based channel estimation has shown its advantage of accurate reconstruction for sparse signal with less pilots for OFDM systems.
However, high computational cost requirement of CS method, due to linear programming, significantly restricts its implementation in practical applications.
In this paper, we propose a reduced complexity channel estimation scheme of modified orthogonal matching pursuit with sliding windows for ISDB-T (Integrated Services Digital Broadcasting for Terrestrial) system.
The proposed scheme can reduce the computational cost by limiting the searching region as well as making effective use of the last estimation result.
In addition, adaptive tracking strategy with sliding sampling window can improve the robustness of CS based methods to guarantee its accuracy of channel matrix reconstruction, even for fast time-variant channels.
The computer simulation demonstrates its impact on improving bit error rate and computational complexity for ISDB-T system.
