Simulation and bit error rate performance of code division multiple access / Muhammad Azwan Ibrahim

Code Division Multiple Access (CDMA) is different than those traditional ways in that it does not allocate frequency or time in user slots but gives the right to use both to all users simultaneously. To do this, a technique known as Spread Spectrum is implemented. The subject of this paper is on data detection and Bit Error Rate (BER) performance of CDMA. The backbone of the project is the CDMA simulation built by using Matlab Simulmk. In this paper, simulation and comparison on the effect of noise and the multipath propagation to the quality of signals in the Direct Sequence Code Division Multiple Access (DS-CDMA) system for both simple non-rake receiver without any special error correction coding mechanism compared with the performance of Rake Receiver.
