This paper proposes a low-complexity compressed sensing (CS)-based time domain channel estimation with virtual oversampling for OFDM-based DTTB system. CS technique is first applied to sparse channel estimation in integrated services digital broadcasting-terrestrial (ISDB-T) system. Unfortunately, the CS-based time-domain channel estimation suffers from a performance degradation under the existence...
Integrated Services Digital Broadcasting - Terrestrial (ISDB-T) is a digital television broadcasting standard that uses orthogonal frequency division multiplexing (OFDM). In mobile environments, the ISDB-T receiver performance is greatly affected by multipath propagation. To mitigate this problem, most in-vehicle ISDB-T receivers use space diversity reception techniques. However, it implies increased...
This paper demonstrates a new approach in reliable channel estimation for Integrated Services Digital Broadcasting Terrestrial (ISDB-T) using Modified Matching Pursuit Algorithm (MMP). The assumption is that the channel characteristic of the succeeding symbols does have correlation with the adjacent symbols. The Matching Pursuit (MP) is used first for solving the channel estimation of the first symbol,...
