摘要：During operation of a cellular system, unexpected growth of traffic may develop in various regions, create traffic congestion. Among many methods to solve problem of large blocking probability, dynamic cell sectoring using smart array antenna is specially interested. In this paper, we investigate the relationship between antenna parameters (main beamwidth, sidelobe attenuation...) and blocking probability of multibeam CDMA system under the presence of hotbeam. From that, we consider deployment sectoring dynamically based on Generalized Sidelobe Canceller (GSC) structure to get blocking probability below 1%. In addition, we consider the way to decrease the complexity of array antenna using sparse array
