中文摘要	A brief introduction to the frequency -domain equalization algorithm based on linear minimum mean square error (LMMSE) is presented, together with its SNR evolution technique. With Gaussian approximation, an issue of designing optimal LDPC is introduced, and the solution is simplified by solving the linear optimization in an iterative way. Simulations are carried out for the optimized LDPC. The result shows that the performance is superior to that given in literature, and is closer to the ultimate system capacity.
