【Abstract】 In this paper, Block interleaved Trellis - Coded - Modulation (TCM) schemes are used for rejecting impulsive noise (IN). Based on an empirical s-mixtrue model for impulsive noise, an upper bound on the performance of TCM is derived, assuming that the receiver performs maximum likeli - hood decoding with perfect side information about channel states. Lots of numerical results are then provided, as further testified by computer simulation.更多还原
