✦ Synopsis


In this paper we present a novel coherent optical code division multiple access system. By exploiting the coherence properties of the source, a reference signal is transmitted along with an encoded signal to achieve coherent detection, so bipolar codes can be used. At the receiver, the desired signal can be recovered using the same code as the transmitter. Secure, asynchronous communication access can also be achieved among many users. This system is described and demonstrated experimentally.

An efficient oscillator active antenna has been designed and demonstrated. The circuit radiates a clean spectrum, and transmits a stable signal with fairly good radiation patterns. The cross-polarization levels were better than 10 dB below copolarization. The antenna provides a dc᎐RF conversion effi

## Abstract A novel multiple user interference (MUI) cancellation technique is introduced with a reference signal which is data‐free from the intended signal. It also simplifies the receiver architecture in synchronous M‐ary wavelength or frequency shift keying (FSK) OCDMA. In the analysis, the sys
