Abstract :
This paper presents a hardware implementation of a Maximum a Posteriori (MAP) decoder system on a soft core processor system which is embedded on an FPGA. The MAP decoder system is developed to perform error correction operations in a wireless baseband transmission through an additive white Gaussian noise (AWGN) channel. The implementation of the decoding algorithm in the soft-core processor system is described. The expected error correction capability with several reconfigurable parameters is shown.
