METHOD AND ARRANGEMENT FOR IMPROVED MODEL ORDER SELECTION

摘要

In a method of enabling model order selection for joint channel synchronization and noise covariance estimation of at least one received signal in a wireless communication network, generating S0 a spatially and temporally stacked signal model by stacking successive samples of temporally adjacent received signal vectors and corresponding training vectors, computing S1 a noise variance matrix for each hypothesized synchronization position, channel length and stacking order, based on the stacked training symbols: determining S2 a best synchronization position for the received signal, based on the stacked training vectors, by jointly determining the best synchronization position for the received signal and estimating a channel length and a stacking order for said signal model based on the stacked training vectors.
