Linear multiuser detectors have been developed for CDMA systems to maintain a balance between the performance and computational complexity of the detectors. However for a system with a large number of users and huge data block length, the cubic complexity of these naive algorithms is computationally prohibitive for real time estimation of transmitted ...

The available wireless bandwidth cannot keep pace with the amazing growth rate of wireless subscribers. Moreover, the higher data rate and superior quality of service demand of the increasingly popular multimedia services over wireless networks mandate efficient utilization of the channel. Unfortunately, the wireless channel is not very conducive ...
