Blind equalisation algorithms for comb-filtereddigital TV signal
Eunjoo Hwang, Wonyong Sung · Electronics Letters · 1999
It has been recommended that digital TV receivers in the USA be equipped with a comb-filter in order to reject co-channel NTSC signals. However, the comb-filtering hinders the use of blind equalisation algorithms that are more robust in dynamic channels. To remedy this problem, the authors have made two modifications, and found that both show satisfactory performances even at an interference level of 0 dB.
