Space diversity reception and parallel blind equalization in short-burst TDMA systems

We consider a -antenna space diversity system combined with two parallel equalizer branches for the reception of short-burst time-division multiple-access signals. By applying a combination of several recently proposed blind equalization algorithms, we make significant improvement over the burst error probability performance reported to date. This is achieved by starting the two blind equalizers from different initial tap settings and applying a specific weighting of the equalizers’ outputs in order to derive the symbol decision. A burst error probability of less than 10 3 is achieved with the new strategy for a root mean square (rms) delay spread of less than 0.4 times the symbol duration. This is a significant improvement over a recently reported result.
