A unique chaotic spreading sequence‐based MC‐CDMA (multi‐carrier code division multiple accesses) is studied in this article. By employing this spreading sequence, interference effect that is inherent in a multi‐user environment can be lessened by deciding on the spreading series with suitable cross‐correlation properties. The simulation study exhibits that chaotic sequence‐based MC‐CDMA acts well...
In this paper a game theoretic approach to study the effect of constellation size on energy efficiency of MC DS CDMA system for M-QAM modulation is studied. A non cooperative game is proposed in which each user seeks to choose its transmit power, transmit symbol rate as well as the constellation size in order to maximize its own utility while satisfying its delay quality of service (QoS) constraint...
This paper presents a novel chaotic spreading sequence for multiple input multiple output multi-carrier direct sequence code division multiple access (MIMO MC-DS/CDMA) systems. The effect of multiple access interference can be mitigated by choosing the spreading sequences with appropriate cross-correlation properties. The performance of the system is analysed in multiuser scenario with the aid of...
A distributed non cooperative power control game with pricing (NPGP) for multiple-input multiple-output (MIMO) multi-carrier direct sequence code division multiple access (MC-DS/ CDMA) system for different modulation is considered in this work. The utility functions for assaying the performance of MIMO MCDS/CDMA for spectral efficient communication of the system carrying wireless data are envisaged...
