Simulation of blind adaptive DS-CDMA LMS detector

Abstract

The contribution is focused on simulation of stochastic adaptive detector of a direct-sequence (DS) spread spectrum signal as a member of code-division multiplex/multiple access (CDM/CDMA). Stochastic gradient-based algorithms, referred to as least mean square (LMS) algorithms have been simulated. This algorithm approximates the autocorrelation function of a stationary input signal by its instantaneous value (stochastic approximation). Some results of simulation are described in the contribution as examples.
