Performance of the turbo coded HomePlug AV system over power-line channels

The next generation technology of HomePlug, called HomePlug AV, aims at providing very high-quality connectivity for the in-home distribution of data and multi-stream entertainment using existing power-line wiring. To obtain very robust performance a powerful turbo convolutional code is adopted. In this paper, by means of simulations, the performance of the turbo coded HomePlug AV system is examined under a realistic power-line channel model. In particular, the effects of the interleaver's length and of the number of iterations in an improved Max-Log-MAP turbo decoder are investigated. Results show that few iterations of the turbo decoding process give a massive gain in performance under the considered environment.
