DVB-RCS and WiMAX Turbo Decoder with Optional Viterbi Decoder

Overview

This is a fully compatible DVB-RCS and IEEE 802.16 WiMAX error control decoder. The decoder can be used to decode the standard 8 state duo-binary tail-biting turbo code or 64 state convolutional code. The PCD03D offers unparalleled speed, performance, low complexity and features compared to other available DVB-RCS or IEEE 802.16 WiMAX decoder cores.
