Ant-colony based optimal MC-CDMA multiuser detector

Hijazi, S. L.; Best, A. J.; Natarajan, B.; Das, S. (Institute of Electrical and Electronics Engineers, 2005)

In this paper, we present a novel multiuser detection (MUD) technique based on ant colony optimization (ACO), for synchronous multi-carrier code division multiple access (MC-CDMA) systems. ACO algorithms are based on the ...
An Evolutionary Approach to Designing Complex Spreading Codes for DS-CDMA

Natarajan, B.; Das, S,; Stevens, D. (Institute of Electrical and Electronics Engineers, 2005)

This paper proposes a novel evolutionary approach to spreading code design in direct sequence code division multiple access (DS-CDMA). Specifically, a multiobjective evolutionary algorithm (EA) is used to generate complex ...
Performance Analysis of Asynchronous Carrier InterferometryMC-CDMA Uplink with Interference Cancellation Techniques

Thippavajjula, V.; Natarajan, B. (Institute of Electrical and Electronics Engineers, 2005)

In this paper, we analyze the uplink performance of an asynchronous carrier interferometry/MC-CDMA, with nonlinear parallel and serial interference cancellation techniques. Specifically, we employ the new variant of parallel ...
