WebCapacity enhancement of CDMA cellular systems with rotatable equal sectoring method in a 2-D urban environment. Authors: M. Godarzvand-Chegini. Electrical Engineering Department, Islamic Azad University, Qazvin Branch, Qazvin, Iran. WebSectorisation is proposed as a method of increasing the system capacity in CDMA/WCDMA cellular systems. However, the obtainable capacity increase is often less than the theoret- ically predicted value. For instance, a 3-sector configuration tends to perform better than the 6-sector system at small cell radii [16] [17].
