Abstract :
Tomlinson-Harashima type precoding for point-to-multipoint transmission over linear dispersive channels which suffer from intersymbol interference and multiuser interference is reviewed. The tasks of the matrix filters at the joint transmitter, their calculation by spectral factorization, and the necessity of an optimized processing order are discussed. The performance of precoding is covered by numerical simulations.
