Abstract
This paper proposed a scattered auxiliary channel subcarriers for OFDM as additional pilots. This will improve the performance of compressed sensing based channel estimation for digital terrestrial TV. The auxiliary channel is designed to convey additional information on modulating signal transmission. The simulation shows that the proposed system has less bit-error-rate compared with the system without scattered auxiliary channel subcarriers. That is because the channel estimation will detect the correct position of the channel impulses with sufficient pilots.
