Coordinated jamming and communications in an MC-CDMA system

A coordinated jamming and communications technique for degrading enemy user transmission performance in a multicarrier code-division multiple-access system is introduced. A linear minimum mean square error (MMSE) algorithm with jamming matrix estimation in single-tone jamming is presented. Furthermore, a blind linear MMSE multiuser detection algorithm in multitone jamming is investigated. Simulation results show that friendly users are able to achieve reliable communications, while the transmission performance of enemy users is significantly degraded.
