A Multiuser Constant Modulus Algorithm for an Antenna Array

摘要：

An adaptive digital filter algorithm that can optimize the signal-to-noise ratio of an antenna array with multiuser signal inputs is presented in this paper. These synchronous communication signals have the constant envelope property and are transmitted through a multiple-input/multiple-output (MIMO) linear channel. This multiuser constant modulus algorithm (MU-CMA) using an antenna array can compensate for both interuser (IUI) and intersymbol interference (ISI). The method is derived by minimizing the cost function of the constant modulus signals as well as cross-correlations between them. The simulation result at the end of this paper shows the performance of this algorithm.
