Abstract
The combination of orthogonal frequency division multiplexing (OFDM) with code division multiple access (CDMA) systems has attained increasing significance in mobile radio communications. In this paper basic OFDM-CDMA detection techniques based on simple equalization algorithms, and improved detection techniques, such as the newly proposed iterative detection applying the minimum mean square error (MMSE) criterion, are analyzed in the mobile radio environment. This analysis enables one a comparison between known and new OFDM-CDMA detection techniques in terms of spectral efficiency and receiver complexity.Keywords
