A path metric computation method and apparatus for estimating a maximum likelihood sequence in a wireless communication network. The proposed method applies the statistical properties of estimated channel impulse response to reduce the computational load. A threshold is set to check the significance of each autocorrelation value in order to determine the contribution to the path metric increment. The corresponding terms in the path metric equation with insignificant autocorrelation values are thus discarded to reduce the complexity of path metric computation.
