Abstract

Abstract

In Short Burst wireless communication and non-corporation communication, the receive data is not long enough to use in Bussgang blind equalization method. In this paper reusing data was introduced to shalvis blind equalization algorithm, by comparing the kurtosis of the reused data after equalizing and the original symbol, the reason of the algorithms valid converging was got. Base on this conclusion, the reusing data method was introduced to Bussgang algorithm. And then the factors which will influent the effect of the reusing data equalization method were analyzed. Simulation results show that reusing data equalization can reduce the symbols of the Bussgang method need to converge, it has some practical utility.
