Subspace tracking based blind multiuser detection: a MMSE estimation approach
Neng Wang, Zheng Baoyu, Zhu Weiping · 2002
A blind multiuser detection scheme based on the signal subspace tracking technique is proposed. Different from some other blind detection schemes, we study the blind detection problem from the perspective of user's parameter estimation in the signal subspace. By using efficient subspace tracking algorithms, this scheme offers better performance and lower computational complexity. Simulation examples are given to compare the performance.
