UNITARY CYCLIC MUSIC ALGORITHM IN A MULTIPATH ENVIRONMENT

摘要

A signal selective Unitary Cyclic MUSIC algorithm is presented by introducing a new forward backward smoothed co-variance matrix. Compared with Cyclic MUSIC algorithm, the suggested approach has a better performance in the presence of multipath propagation. In addition,this approach not only reduces the computational complexity by real-valued eigendecomposition, but also allows to select desired signals and to ignore interferences by exploiting the cyclostationar-ity property of signals of interest (SOIs). Simulation results that illustrate the performance of this approach in conjunction with Cyclic MUSIC algorithm are described.
