Novel subcarrier-allocation schemes for downlink MC DS-CDMA systems [PDF]
IEEE Transactions on Wireless Communications, 2014 This paper addresses the subcarrier allocation in downlink multicarrier direct-sequence code-division multiple access (MC DS-CDMA) systems, where one subcarrier may be assigned to several users who are then distinguished from each other by their unique ...

Ant-Colony-Based Multiuser Detection for MC DS-CDMA Systems [PDF]
2007 IEEE 66th Vehicular Technology Conference, 2007 In this contribution we present a novel ant colony optimization (ACO) based multi-user detector (MUD) designed for synchronous multi-carrier direct sequence code division multiple access (MC DSCDMA) systems. The operation of the ACO-based MUD is based on

Layered Steered Space–Time-Spreading-Aided Generalized MC DS-CDMA [PDF]
IEEE Transactions on Vehicular Technology, 2010 —We present a novel trifunctional multiple-input– multiple-output (MIMO) scheme that intrinsically amalgamates space–time spreading (STS) to achieve a diversity gain and a Vertical Bell Labs layered space–time (V-BLAST) scheme to attain a multiplexing ...

Space-time spreading assisted broadband MC DS-CDMA [PDF]
Vehicular Technology Conference. IEEE 55th Vehicular Technology Conference. VTC Spring 2002 (Cat. No.02CH37367), 2003 In this article multicarrier direct-sequence code-division multiple-access (MC DS-CDMA) using space-time spreading (STS) is investigated in the context of broadband communications over frequency-selective Rayleigh fading channels. We consider a range of design issues as well as the achievable bit error rate (BER) performance for the down-link, by ...

The effect of carrier phase jitter on MC-DS-CDMA
ICC 2001. IEEE International Conference on Communications. Conference Record (Cat. No.01CH37240), 2002 We study the effect of carrier phase jitter on the performance of both uplink and downlink multicarrier direct-sequence CDMA (MC-DS-CDMA). We determine the resulting performance degradation in terms of the various systems parameters. Assuming an AWGN channel, perfect power control and full load, it is shown that this degradation is independent of the ...
