摘要
A novel adaptive array receiver algorithm in the WCDMA uplink, which the LSCMA can be smoothly switched to the LS-DRMTA is presented. Firstly, we propose a convex combination approach by running the LSCMA and LS-DRMTA algorithms simultaneously to obtain a smooth switch between them, which is guaranteed by the basic theory of convex combination method. Then an "anchoring process" is described to implement fast user tracking by exploiting the in-buid pilot signal. The overall receiver can be regarded as the LS-DRMTA algorithm being anchored by the combination adaptive algorithm. Analysis demonstrates that our proposed algorithm has the good convergence properties and low computational complexity, which is also verified by the numerical simulations.
