The Study on Improving the Interference Immunity of Commercial Wireless Communication Based on Adaptive Strategy

In this paper, a typical commercial short range wireless communication module which has weak immunity to interference has been tested and its performance has been evaluated with test bed. An adaptive frequency hopping scheme has been proposed to filter of spatial channel which has the spatial and temporal focusing. The adaptive frequency hopping scheme is help to alleviate the multi-user interference, inter-symbol interference and co-channel interference. This paper introduces briefly the basic concepts and characteristics of the commercial wireless communication, comparing with the traditional technique, gives a comprehensive survey on the application.
