A High-Resolution Iterative DOA Algorithm for CDMA System
Liu Wen-ke, Liang Jin, Hu Junjie, Baowei Cheng · 2006
In this paper, an iterative high-resolution DOA algorithm is presented for DOA estimation for CDMA systems. The algorithm iteratively removes detected signals from the received data and searches the residue spatial spectrum for further signals. It does not require any computationally expensive eigen decomposition or spatial smoothing in coherent multipath scenarios. Results are presented illustrating high-resolution at significantly lower SNR levels than those obtained by classical DOA algorithms such as MUSIC and MVM
