Capacity optimisation in MC‐CDMA systems

European Transactions on Telecommunications, 2002
AbstractA novel efficient algorithm is proposed for the optimisation of capacity assignment in a MC‐CDMA system with an additional frequency division multiplexing component. Based on an estimate of the frequency‐selective channel, the algorithm optimises the assignment of the sub‐bands to the users with respect to the overall system capacity. Moreover,

On optimization of CI/MC-CDMA system

2009 IEEE 20th International Symposium on Personal, Indoor and Mobile Radio Communications, 2009
This paper proposes a new model of high capacity carrier interferometry/multicarrier code division multiple access (CI/MCCDMA) system through the simultaneous support of high and low data rate transmission using odd and even subcarriers. Reduction in peak-to-average power ratio (PAPR) is achieved through the phase shift of even (odd) CI code using odd (

Performance analysis of MC-CDMA system

2012 1st International Conference on Recent Advances in Information Technology (RAIT), 2012
To achieve high data rate Multi-Carrier Code Division Multiple Access (MC-CDMA) is one suitable choice for next generation wireless communication system. MC-CDMA is the combination of CDMA and OFDM schemes, resulting into getting the advantages of both the schemes.

A MC-CDMA system based on CMFB

Proceedings of the 2004 IEEE International Conference on Control Applications, 2004., 2005
An M-band CMFB with a side lobe of about 45 dB was designed using the optimum equal wave method. Modulation was made with the updated comprehensive filter banks, and demodulation was made with the analytic filter banks, and a multi-carrier CDMA system based on CMFB was constructed.

Performance Analysis and Comparison of Coded FH/MC-CDMA and MC-CDMA Communication System

2007 IEEE 18th International Symposium on Personal, Indoor and Mobile Radio Communications, 2007
In this paper, we will combine the frequency hopping (FH) and the multi-carrier code division multiple access scheme (MC-CDMA) through an internal coding. The total bandwidth will be divided to a number of sub-bands with equal bandwidth. In each signalling interval, the output of a super orthogonal encoder selects one of the sub-bands for data ...
