Importance sampling for TCM scheme on additive non-Gaussian noise channel

摘要

Some error probability estimation methods of a trellis-coded modulation (TCM) scheme using importance sampling have been previously proposed (Sadowsky, 1990). However, these methods are not suitable for an additive non-Gaussian noise channel case. The main problem is how to design the probability density function in importance sampling. We propose a new design method of the probability density function related to the Bhattacharyya bound.
