On the use of interference suppression to reduce intermodulation distortion in multicarrier CDMA systems.

On the use of interference suppression to reduce intermodulation distortion in multicarrier CDMA systems.

This paper presents a coded multicarrier direct-sequence code-division multiple-access (DS-CDMA) system that, by the use of a minimum mean-squared-error receiver, achieves frequency diversity (instead of path diversity as in a conventional single-carrier RAKE DS-CDMA) and has the ability to suppress...
