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...
Impulsive noise interference is a significant problem for the Integrated Services Digital Broadcasting for Terrestrial (ISDB-T) receivers due to its effect on the orthogonal frequency division multiplexing (OFDM) signal. In this paper, an adaptive scheme to suppress the effect of impulsive noise is proposed. The impact of impulsive noise can be detected by using the guard band in the frequency domain;...
