Optical Code Division Multiple Access Systems
The optical code division multiple access (optical CDMA) systems is a versatile multiple access technique as compared to time division multiple access (TDMA) and wavelength division multiple access (WDMA). In optical CDMA, the users are assigned unique codes whereas the WDMA and TDMA systems users are assigned different wavelengths or time slots so as to distinguish the data recovered at the re...
متن کاملGroup detection for synchronous Gaussian code-division multiple-access channels
The concept of group detection is introduced to address the design of suboptimum multiuser detectors for CodeDivision Multiple-Access (CDMA) channels. A group detection scheme consists of a bank of P group detectors, one each for detecting the information symbols of users in each group of a P group partition of the li simultaneously transmitting users. In a parallel group detection scheme, thes...
متن کاملRandom Sequence Multisets for Synchronous Code-Division Multiple-Access Channels
The effect of using randomly selected sequence multisets for the uplink of a synchronous code-division multipleaccess channel is considered. A tight lower bound on the expected value of the sum capacity over the ensemble of randomly selected sequence multisets is given. For large systems, the sum rate penalty for using randomly selected multisets is shown to be at most 1 nat and to vanish as th...
متن کاملLinear multiuser detectors for synchronous code-division multiple-access channels
In code-division multiple-access systems, simultaneous multiuser accessing of a common channel is made possible by assigning a signature waveform to each user. Knowledge of these waveforms enables the receiver to demodulate the data streams of each user, upon observation of the sum of the transmitted signals, perturbed by additive noise. Under the assumptions of symbol-synchronous transmissions...
متن کاملWavelength Division vs. Code Division Access Methods for Optical Networks
This paper examines two methods of multiple access for optical networks: code-division and wavelength division. Two approaches are given for analyzing code-division systems, and an overview of a proposal for a WDM network will be summarized. Since the maturity of the technologies necessary for such systems diier, the usefulness of a direct comparison between CDMA and WDM is limited; instead, th...
