Abstract:
A semiblind approach for equalization and jammers rejection at the base station in wireless communications is presented. It is based on the idea of enlarging the effective length of a known short training sequence by using a few additional information symbols and the finite alphabet property of the communication signals. Simulation results for spatio-temporal processing of 4-QPSK signals transmitted by simultaneous intracell users demonstrate the advantage of the proposed approach in situations where the length of the training sequence is not large enough to allow estimation of the desired signal with previously proposed methods
