TETRA-TEDS Turbo Decoder with Optional Viterbi Decoder

Overview

This is a fully compatible TETRA-TEDS error control decoder. The decoder can be used to decode the standard 8 state turbo code and 16 state convolutional code. The PCD03T offers paralleleled speed, performance, low complexity and features compared to other available decoder cores.
