Generalized selection combining scheme with double threshold in the soft handover region

A new diversity selection combining scheme in a multiple Base Stations (BSs) scenario is proposed, in order to minimize the impact of suddenly losing one active BS in the soft handover (SHO) region. By analyzing the average number of path estimations and the average number of combined paths, we can see that the proposed scheme has a satisfactory average bit error ratio (ABER) but with a low complexity, as compared by the conventional distributed combining schemes. Simulation results validate the superiority of the proposed scheme.
