英文摘要：

Equalization is widely adopted to reduce the inter-symbol interference （ISI）. The blind equalization algorithm based on Bussgang technology is easy to achieve, whose resource and computation can be reduced and convergence can be speeded up when simplifying symbols. The principle of blind equalization based on Bussgang is analyzed, the convergence speed of proposed algorithms are compared, the development trend of blind equalization algorithm is proposed.
