A novel constant modulus array for multiuser detection
A novel multitarget constant modulus array structure is proposed for CDMA systems in this paper. The new algorithm for the structure is called predespreading and wavelet denoising constant modulus algorithm (D-WD-CMA). In the new algorithm, the predespreading and wavelet denoising are applied for multitarget arrays to remove some multiple access. Simulation results illustrate the good performance for the proposed algorithm, compared with the traditional CMA algorithm.
