MULTfflOP MOBILE CELLULAR NETWORK

Code Division Multiple Access (CDMA) system capacity is interference limited.
Distance of the mobile station (MS) to the base station (BS) affects the capacity and
interference of a cellular network system. Relaying is to shorter the distance between
BS and MS by adding a relay station (RS) between them. Transmission power is
smaller due to shorter distance and thus improves the capacityof the CDMAsystem
due to reduction in interference. Relaying can be done by using fixed relay station or
mobile relay station. Both objectives are to improve the capacity and reduce
interference but they are different since fixed relay station is constructed on land or
building while mobile relay station is additional features added into mobile phones.
This project shows the benefits of multihop with mobile relay station which improve
the interference by relaying compared to thesystem without relaying.
