Design and Study of Direct Sequence - CDMA RAKE Rx Simulator for Wireless Communication
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2013, Vol 2, Issue 9
Abstract
In this paper, a software wireless communication simulator execute to simulate a Code division Multiple Access (CDMA) as Wireless cellular telephony has been growing at a quicker rate than wired-line telephone networks. This development has been fuelled by the recent improvements in the capacity of wireless links due to the use of multiple access techniques (which allow many users to share the same channel for transmission) in association with advanced signal processing algorithms. The backbone of this system is a wireless CDMA single user link built using Mat lab. An efficient method of system modelling is used to get rap out the simulations. The simulator is a tool to estimate these design opinions and trades in different circumstances. This simulator can be used to study the recital of a CDMA wireless link with variation in system parameters and channel conditions. In this simulator we can modify the attenuation factor and simulate CDMA with RAKE receiver and without RAKE receiver, the transmitted data and received data is illustrate in form of graph, we can compare the received statistics with and without RAKE receiver for dissimilar attenuation factor.
