Abstract :
The coherent reception of direct sequence-code division multiple access (DS-CDMA) is considered, when chaotic sequences are used instead of conventional pseudo-noise (PN) spreading code. 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 single user case is presented.
