On the Selection of Cellular Automata based PRNG in Code Division Multiple Access Communications
The main contribution of this article is to investigate the application suitability of Cellular Automata based pseudo-random noise generator in Code Division Multiple Access Communications. New dynamics in group Cellular Automata were explored. Extensive analysis for two classes of group Cellular Automata (maximum length Cellular Automata and equal length Cellular Automata) were carried out. Th...
متن کاملConvolutional Coding Strategies for Code Division Multiple Access Cellular Communications
This paper investigates the use of non-linear convolutional coding techniques for use in a DS-CDMA cellular communication system. Comparisons are made between various error-correction strategies and the Wiener minimum mean square error receiver filter, implemented with the same bandwidth expansion. The use of Gold codes in conjunction with an orthogonal convolutional encoder is shown to produce...
متن کاملImproved Multiuser Detection in Code-division Multiple Access Communications
In Code Division Multiple Access (CDMA) communications, Multiuser Detection (MUD), that reduces the multi-access interference (MAI) and that solves the near-far problem, has been widely studied for over 15 years. Since optimal multiuser detection is generally NP hard, many sub-optimal algorithms that provide reliable performance and ensure polynomial complexity have been proposed. However, ther...
متن کاملTruncated power control in code-division multiple-access communications
We analyze the performance of truncated power control in a code-division multiple-access (CDMA) communication system. This power control scheme compensates for propagation gain above a certain cutoff fade depth: below the cutoff level, data transmission is suspended. We assume a channel with fast Rayleigh fading and slow lognormal shadowing plus path loss, where truncated power control is appli...

Code Division Multiple Access Communications Sang Wu Kim1 and Andrea Goldsmith Dept. of Electrical Engineering California Institute of Technology Pasadena, CA 91125 Abstract We analyze the performance of the truncated power control scheme in code division multiple access communication systems, which compensates for fading above a certain cuto fade depth. We investigate the power gain as well as...
