|Title:||Design of a high-speed MC-CDMA system for broadband mobile radio communications||Authors:||Madhukumar, A.S.
|Issue Date:||2001||Citation:||Madhukumar, A.S.,Chin, F. (2001). Design of a high-speed MC-CDMA system for broadband mobile radio communications.

ScholarBank@NUS Repository.||Abstract:||This paper is concerned with a new method to enhance the bandwidth efficiency of an MC-CDMA system by using a residue number based representation for information symbols. The residues are mapped into a set of orthogonal sequences and are transmitted in parallel. To increase the data rate further, a modified residue representation scheme is used with significantly less number of orthogonal sequences. A multicarrier modulation scheme is used for both transmission and reception of residue channels. The issues involved in the design of an enhanced RNS based MC-CDMA architecture is discussed and the performance of the system is evaluated in a frequency selective Rayleigh fading channel via extensive simulations.||Source Title:||IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, PIMRC||URI:||http://scholarbank.nus.edu.sg/handle/10635/112326|
