ii In the growing world of communications, where speed and is the key, and more and more users need to share the limited bandwidth, a faster signal detection method is needed. Since channel bandwidth is limited and not infinite, especially in wireless communications, and everyday there are more devices and users competing for the already precious commodity, the bandwidth must be shared. Current communication systems use a process called CDMA (Code Division Multi Access) to “share ” a single carrier frequency. While this conserves bandwidth, it brings into question the idea of determining which user sends what signal. There are many methods of detecting these signals, but as there are more and more users on the channel, and people want faster speeds, the detection methods become very complex and require lots of computing power to keep up with the demand. What the Low Complexity Signal Detection project entails is studying the current suboptimal detectors and the “optimal detector ” and its performance under differen
