“…The ATSC "threshold of visibility" (TOV) is defined as the lowest signal to noise ratio (SNR) at the input to the receiver which yields a segment (or Reed-Solomon codeword) error rate of 2 × 10 -4 [1], corresponding to a SER of approximately 0.2 at the equalizer output [6]. At higher error rates the picture quality is deemed to be unacceptable.…”

“…Decision feedback equalizer (DFE) is a well tradeoff between MLSE with prohibitive implementation and linear equalizers with poor performance in severe channels [1][2] . Consequently, LMS DFE is preferred in the ATSC DTV receivers [3][4] . In the DTV channel, echo delay is often up to hundreds of symbols.…”

Adaptive LMS-DFE is preferred as an effective solution to coping with inter-symbol interference (ISI) for ATSC DTV receivers. In the DTV channel, echo delay often covers hundreds of symbols, by performance constrains, which leads to very large-scale equalizer with huge computational complexity. One consequence of the adaptive large-scale equalizer is that of very slow convergence. It is combined with error propagation, the inherent drawback of DFE, seriously deteriorating the performance of the receivers, especially in severe channels. In this paper, we apply the subband processing to LMS DFE for sufficient speed of convergence, trying to open the eye diagram until the end of train sequence. It is ready for the decisiondirected mode. Simulation results show that the proposed scheme improves the performance of the equalizer, especially in severe channels.

“…Receivers have become increasingly reliable in difficult channel conditions, such as indoor reception in urban settings, where dense multipath can heavily impair the transmitted signal. The current state-of-theart ATSC reception scheme employs decision feedback equalization (DFE) [4,5]. To handle difficult channels, receiver complexityin particular, the DFE filter length-has increased significantly.…”

This work proposes a frequency domain turbo equalization (FDTE) scheme for the reception of transmissions that employ vestigial sideband modulation and punctured trellis coding, as specified by the ATSC North American terrestrial digital television (DTV) standard. The proposed FDTE scheme enables low-cost and high performance reception of highly impaired DTV signals. Through numerical simulation, we demonstrate that our FDTE scheme outperforms the traditional joint DFE/decoding approach at a fraction of the implementation cost.
