Abstract :
A coherent optical CDMA network employing Gold sequences for the spreading and despreading operations is analysed in terms of the signal to noise ratio penalty as a function of the number of simultaneous users incurred to maintain a given value of the bit error rate. The binary PSK and OOK modulation schemes are considered. Exact results in the presence of noise and interfering signals (interferers) are obtained.
