3GPP UMTS LTE 3GPP2 cdma2000 1xEV-DV 1xEV-DO Turbo Decoder with Optional Viterbi Decoder

This is a fully compatible 3GPP (UMTS and LTE) and 3GPP2 cdma2000 (1xEV-DV Release D and 1xEV-DO Release B) error control decoder.

Overview

This is a fully compatible 3GPP (UMTS and LTE) and 3GPP2 cdma2000 (1xEV-DV Release D and 1xEV-DO Release B) error control decoder. The decoder can be used to decode the standard 3GPP or 3GPP2 8 state turbo code and 16, 32, 64 or 256 state convolutional codes. The PCD03V offers unparalleled speed, performance, low complexity and features compared to other available 3GPP or 3GPP2 decoder cores.
