Authors: Mr. Suyeb Ahmed Khan, Dr. Jasvir Singh, Dr. Mahmood Mian
Abstract:
Multiuser detection technique has been applied for capacity enhancement in the presence of loading, voice activity, sectorization, inter & intra interference in multicell scenario of third 3G WCDMA system. In CDMA based system, each user transmits a data sequences spreaded by a code. This code is Unique to the mobile station (MS) and base station (BS) on both uplink and downlink. The present paper deals with capacity in term of number of user in single and multicell environment in the presence of capacity influencing factor at a constant power of the base station in a CDMA based system operating in downlink FDD mode at 5 MHz bandwidth
