Abstract :
The multiuser asymptotically robust invariant demodulation algorithm for CDMA systems is considered. It provides multiple access interference (MAI) suppression and does not require controlling of power of mobile transmitters. In addition, the algorithm provides high quality demodulation under the conditions of non-Gaussian noise. The algorithm characteristics were obtained by computer simulation for the case of binary differential phase modulation.
