Abstract :
This paper describes an anti-jamming algorithm in DS-CDMA cellular system. The proposed algorithm consists of detection, verification and control module. The detection module is based on the investigation of user´s Eb/No received at the channel element (CE) of Base Station (BS) for finding jamming MS when all the SNRs of the mobile stations are greater than the threshold SNR. The verification module verifies whether the MS is jamming MS or not. The control module is based on the disconnection of the active call of jamming MS. Therefore, we can prevent the cell coverage from shrinking due to jamming MS. As a result, we can locate the jamming MS using the proposed anti-jamming algorithm in a CDMA cellular system and prevent the cell coverage from shrinking due to the jamming MS and decrease the load of system by hand-off
