Iterative equalization method and equipment for single-carrier broadband wireless communication system

The invention relates to an iterative equalization method and equipment for a single-carrier broadband wireless communication system, and the method comprises the steps: obtaining initial coding bit external information and an initial estimation value of an original information bit data flow in an initial state, and carrying out the processing through employing a time domain iterative equalizationstructure at a receiving end in iteration, and particularly designing a feedback filter bank and a feedforward filter structure; jointly optimizing coefficients of the feedback filter bank and the feedforward filter; estimating related parameters in the filter coefficients; calculating an equivalent signal-to-noise ratio of the equalization signal; and carrying out MAP decoding on the equalization signal to obtain an estimated value of the original information bit data stream of the ith iteration and the coding bit external information of the ith iteration for the next iteration. Meanwhile, the invention provides a d
