Fast recovery equalization techniques for DTV signals
Nitish Vikas Deshpande · IEEE Transactions on Broadcasting · 1997
Blind equalizers do not require any training sequence for the initial startup period but rather perform equalization blindly on the data directly. In this paper, a general approach for designing such equalizers for 8-VSB transmission systems is presented. The candidate algorithms considered here include Godard's algorithm (Godard 1980), Sato's algorithm (Sato 1975), the G-pseudo error algorithm using Sato's function and the G-pseudo error algorithm using Godard's function. This paper analyzes these algorithms for the 8-VSB transmission format and recommends the most suitable algorithm. The performance comparison parameters include MSE, convergence characteristics, computational load and accuracy of estimating the channel.
