Abstract :
Under the synchronous condition, based on the character of the receiving signal constructs, a new decorrelating decision feedback method with successive interference cancellation is obtained. With this new sub-optimal method, not only can the computation of the reverse matrix of the correlating matrix be avoided, but also the computing complexity does validly decrease,the simulation and example also support this conclusion.
