  journal={IEEE Trans. Communications},
Recently, Wang and Høst-Madsen developed group-blind multiuser detectors for use in code-division multiple-access (CDMA) uplink environments in which the base station receiver has the knowledge of the spreading sequences of all the users within the cell, but not that of the users from other cells. Yu and Høst-Madsen later developed an adaptive version of this detector for synchronous CDMA channels. In this letter, we develop a new low-complexity, high-performance subspace tracking algorithm and… CONTINUE READING
