The Study On Blind Maximum Likelihood Sequence Estimation Algorithm

Blind equalization is a newly adaptive equalization algorithm for adapting an equalizer without the need of training sequence, only utilizes the received channel output signal to equalize the channel character. It is not only one of three antifading techniques in mobile communication system, but also the advanced research subject in communication and signal processing field. With the researching of blind equalization, it has been used in many fields such as communication, sonar, radar, earthquake prospecting, biomedicine engineering, control engineering and so on. The blind maximum likelihood sequence estimation algorithm , a main algorithm in blind equalization field, has been becoming a very popular research topic at home and abroad.The major contribution of this paper is summarized as follow(1) The present status on blind MLSE algorithm has been studied in this paper. Blind equalization algorithms based on maximum likelihood sequence estimation is firstly classified as blind equalization algorithms of...
