Multiple Access Techniques is the emerging techniques for the next generation (3G) wireless communication systems. Multiple access techniques has been designed to add features such as multimedia capabilities, high data rates and multi-rate services to the existing wireless communication framework. The data rates proposed 2, 3 are 2Mbps indoor, 384 Kbps pedestrian, and 144 Kbps vehicular. Several standards for third generation systems have been proposed and developed by different industrial committees in countries such as the U.S, Europe and Japan. All the standards have accepted in one form or another as the multiple access method for wireless communications requirements. In this project, we study the implementation issues involved for one of the proposed multiuser channel estimation and detection algorithms for base-stations. It was found that these proposed algorithms for multiuser channel estimation and detection have different processing and precision requirements.
