摘要
En 中文
We propose a blind multiuser detection technique for array processing and code division multiple access (CDMA) systems that does not require knowledge of the array geometry or transmitter signature sequences. The technique has two hey elements: an adaptive algorithm for separating the signal subspace from the noise subspace and an adaptive whitener based on linens prediction. The proposed algorithm offers low complexity, fast convergence, compatibility dth shaped signal constellations, near-Wiener steady-state performance, and optimal near-far resistance.
