摘要：The aim of our study is to find by means of compute simulations the pair of a receiver and a set of thespreading codes able to provide the best BER performance under the mentioned conditions. The simulation resultsshows that the maximum improvement of the MC-CDMA. This project is to investigate the MUD scheme, and realize afully functional system in software for developing an algorithm for the detection of multi-users in CDMA system byusing a noisy gradient approach. Several techniques are under consideration for the next generation of digital mobilesystems, with the aim of improving cell capacity, multi path immunity and flexibilities. These include CDMA andOFDMA. Both these techniques could be applied to providing a fixed wireless system for rural areas. However, eachtechnique as different properties, making it more suited for specific applications and this technique is implemented byMATLAB.
