Frequency Domain Turbo Equalization for Vestigial Sideband Modulation with Punctured Trellis Coding

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
