Summary:
In this paper a coherent reception of direct sequence-code division multiple access (DS-CDMA) in multi user case (MU) is considered, when chaotic sequences are used instead of conventional pseudo-noise (PN) spreading codes. A piecewise linear map (PWL) is used as chaotic spreading sequence (CSS). Additive white Gaussian noise channel (AWGN) is assumed. An analytical expression of the bit error rate in the multi user case is presented.
