A New Neighbor Discovery Scheme Based on Spatial Correlation of Wireless Channel

We propose a new neighbor discovery scheme for cellular communication systems that utilizes the azimuth spread (AS), delay spread (DS) and shadow fading of a mobile station (MS). Given that the AS, DS and shadow fading are spatially correlated, MSs that are close to each other will have similar AS, DS and shadow fading values. In our proposed scheme, we use the AS, DS and shadow fading of an MS to find its neighbor MSs. The proposed scheme filters out MSs that are unlikely to be neighbor MSs and uses the Kolmogorov-Smirnov (K-S) test for more refined neighbor discovery. Through analysis and simulation, it is shown that we can effectively find neighbor MSs.
