Abstract :
A new multiuser detection algorithm based on signal subspace tracking is proposed, and compared with the previous RLS minimum-output-energy (MOE) blind adaptive multiuser detector. The proposed algorithm offers lower computational complexity, better performance and robustness against signature waveform mismatch.
