A maximum a posteriori probability (MAP) detector based on a forward only algorithm with high throughput is considered in this paper. MAP gives the optimal performance and, with Turbo decoding, can achieve performance close to the channel capacity limits. Deep pipelined architecture for the forward only method is presented and compared with the other throughput-increasing methods. Simulation results based on the iterative MAP-LDPC (low-density parity check) system are shown. Hardware implementation issues that exploit the regularities of the structure are also discussed.
