In this paper, using the idea of encoding, an improved quasi-MLSE equalization algorithm is proposed based on Viterbi algorithm. This algorithm can greatly reduce the computational complexity and has the characteristics of low sensitivity to channel impulse response waveform and compatibility with soft output Viterbi algorithm. In this paper, we use computer to simulate the performance of the algorithm, and compare with the algorithm such as NMLSE. The simulation results show that the algorithm has good anti-ISI performance.
