The TCC decoder is used in conjunction with a TCC encoder to provide an extremely effective way of transmitting data reliably over noisy data channels. The Turbo decoder operates very well under low signal to noise conditions and provides a performance close to the theoretical optimal performance as defined by the Shannon limit. This version of the TCC (Turbo Convolution Code)decoder is designed to meet the 3GPP mobile communication system specification.
