In communication systems, the recombination of asynchronous signals frequently results in a signal totally deformed. This paper takes up with a novel first recursive method based on the combination of Least Mean Squares (LMS) algorithm and blind equalization, which aims at doubling the Signal to Noise Ratio (SNR) of the recombined signal compared to the original one. Two cases are studied in this paper for the application of the proposed method: before and after demodulation, respectively. The simulations are conducted to verify the feasibility of the proposed algorithm and the obtained comparison results demonstrate that the post-demodulation case is much superior to that of predemodulation, in the implementation capability of the realized filters.
