We present a design method of the simulation probability density function for a trellis-coded modulation(TCM)in an impulsive noise environment. The upper bound evaluation method for the TCM scheme cannot be applied to the lognormally distributed impulsive noise, since the Chernoff bound cannot be defined. Thus the error pobability can only be estimated by a computer simulation. For an evaluation of a low error probability, importance sampling(IS)is an efficient technique. A design method of the simulation probability density function, which plays an important role in IS, is proposed for the noise. The effectivity is shown by a numerical example.
