Abstract :
This paper describes the FPGA implementation of a 3GPP compliant TCC (turbo convolutional codes) codec. The decoder employs the MAP algorithm, utilizing the max* operator, and achieves a BER of 10/sup -6/ for a 1.5 dB SNR. In addition to providing an overview of the datapath architecture, the C based design and verification methodology is presented.
