Abstract :
In this paper, we propose a low-complexity soft-output channel detector for turbo equalization over coded partial-response channels based on the simulated annealing (SA) algorithm. It is shown that the proposed detector can significantly reduce the computational complexity with only slight performance degradation compared to the BCJR algorithm
