In order to overcome the defects of traditional constant modulus blind equalization algorithm in equalizing higher-order QAM(Quadrature Amplitude Modulation) signals, on the basis of combining the momentum term algorithm and the weighted multi-modulus blind equalization algorithm, Momentum term based Weighted Multi-Modulus blind equalization Algorithm(WMMA) is proposed. In the proposed algorithm, weighted multi-modulus blind equalization algorithm is used to adjust the modulus of the cost function adaptively and momentum term is employed to improve the convergence speed. The simulation results in the underwater acoustic channel show that the proposed algorithm has higher convergence speed and accuracy than Multi-Modulus blind equalization Algorithm(MMA) and Constant Modulus blind equalization Algorithm(CMA).

The problem solved in this paper is to design a video streaming protocol which is accomplished by the application layer multicast in the WLANThis protocol, WVALM, divides the whole video streaming into small blocks, and achieves the requirement of streaming multicast by multicasting those small blocksThe receiver and the sender use streaming window and retransmit window respectively to coordinate their relationshipThrough experiment test, WVALM achieves the original object and could work well in the wireless environment.
