Abstract
A method for long-term evolution (LTE) synchronization by a signal receiver in the presence of interference signals including providing multiple parallel adaptive filters to eliminate the contribution of an interference signal to a timing metric of an LTE signal; wherein coefficients of each of the parallel adaptive filters are determined using a linearly constrained minimum variance (LCMV) criterion to minimize output power of each filter subject to the LCMV criterion that preserves received signal vectors corresponding to all possible primary synchronization signal signatures; and wherein the LCMV criterion are updated iteratively using a recursive least squares (RLS) algorithm.
