A Capacity Comparison Between MC-CDMA and CP-CDMA
IEEE Vehicular Technology Conference, 2006In this paper, we consider the capacity behaviors of MC-CDMA and CP-CDMA systems by the uses of MMSE receivers. The averaged capacities are derived for the two systems, having a finite spreading factor, in Rayleigh fading environment. The closed-form solutions have been obtained, which show that the capacity of the MC-CDMA is slightly larger than that ...

DS-CDMA, MC-CDMA and MT-CDMA for mobile multi-media communications
Proceedings of Vehicular Technology Conference - VTC, 2002We present a comparison between direct sequence code division multiple access (DS-CDMA), multi-carrier (MC-) CDMA and multitone (MT-) CDMA schemes in terms of the transmitter and receiver structure. We discuss their down-link bit error rate performance in a frequency selective Rayleigh fading channel by computer simulation.

CDMA mobile stations using the North American cellular system rely upon the IS-41 network protocol for intersystem handoff and roaming. This paper describes the IS-95 air interface and corresponding IS-41 protocols for intersystem handoff, mobile station location determination, and call delivery.

Proceedings of the Sixth IEEE Computer Society Workshop on Future Trends of Distributed Computing Systems, 2002
This paper shows how reliable data services can be provided in an error prone wireless environment using CDMA and a link layer retransmission protocol. A CDMA encoder using Walsh codes for 1.85 to 1.99 GHz PCS applications is simulated under various error conditions with varying packet size to determine minimum acceptable QOS relative to error ...

The authors present an overview of new multiple access schemes based on a combination of code division and multicarrier techniques, such as multicarrier code-division multiple access (MC-CDMA), multicarrier direct sequence CDMA (multicarrier DS-CDMA), and multitone CDMA (MT-CDMA).
