?In this paper a new diversity selection combining scheme called SSB (simplified switched beam) is given, as well as its test-bed implementation. SSB has apparent advantage in terms of size, power and complexity since it only requires one RF front-end and very few additional components. Furthermore, an interference suppression technique is designed, which can effectively mitigate the disturbance on correct diversity selection caused by interference. The intensive measurements made in an indoor environment show that this test-bed can closely approach the theoretical prediction on SNR gain and AF (amount of fading).
