Abstract Referring to the problem of inter-symbol interference in
communication channel, an adaptive equalization algorithm based on
the new quasi-Newton method is proposed. Using the positive definite
symmetric Hesse matrix iteration formula instead of autocorrelation
function inverse matrix, the proposed algorithm overcomes the
influences caused by the step factor and the signal autocorrelation
function estimation on the convergence speed and steady-state error.
Simulation results show that the proposed algorithm has fast
convergence speed and low bit error rate within the large step.
