Abstract
Process of signal detection for homodyne correlation receiver using dual balanced detector is described. The spreading sequence, prime code, is a unipolar code always encoded in form of optical pulse intensity. A complete receiver model is set up including equivalent receiver circuit noise and shot noise at the receiver as well as the multiuser interference; it makes possible to estimate the system performance from a single user to multiple users. According to this model, the system performance can also be evaluated depending not only on the number of simultaneous users but also on other parameters such as chip pulse power, equivalent receiver circuit noise, and responsivity of photo detector.
