Single tone jamming elimination scheme of multicarrier spread spectrum system
Journal of Electronics, 2004The proposed scheme is based on Discrete Fourier Transform (DFT) domain processing. The key technology of this scheme is jamming parameters’ accurate estimation and jamming reconstruction. Compared with the “threshold exciser” scheme the proposed scheme can eliminate more jamming energy on the whole frequency band with the minimum loss of useful signal

The performance evaluation of transmitted reference UWB in the presence of single-tone jamming
2009 International Conference on Communications, Circuits and Systems, 2009The traditional receiver is not optimal receiver from point view of minimum BER performance in the presence of single-tone jamming. For the proposed receiver the fixed part of the multiplier output is cancelled before integral or combination. The proposed receiver can mitigate the single-tone jamming efficiently.

The performance of a kind of CDMA receivers in single-tone jamming environment
Proceedings of ISSSTA'95 International Symposium on Spread Spectrum Techniques and Applications, 2002A synchronous CDMA communication system in a tone jamming environment is considered. The bit error rate of an anti-multiple-access interference single-user detection receiver is given. The demodulation sequence supplied by a control center doesn't equal the signature sequence.

Performance of the direct sequence spread spectrum system with single-tone jamming
2010 IEEE International Conference on Information Theory and Information Security, 2010The current analysis focuses on the performance of DSSS system with single-tone jamming. From the analysis we can conclude that the bit error rate not only relates to signal-to-noise ratio (SNR) and jamming-to-signal ratio (JSR), it will be also influenced by the pseudonoise (PN) sequence, frequency or phase difference of the jamming and communication ...

Time-Varying Single Tone Jamming Suppression Based on Frequency Interference Cancellation
International Journal of Signal Processing, Image Processing and Pattern Recognition, 2013The goal of this paper is to suppress time-varying single tone jamming (STJ) in the CDMA system by using the frequency interference cancellation method. We consider the practical scenario where STJ signal experiences time-varying fading channel. In this approach, the parameters (i.e. frequency, amplitude and phase) of the time-varying STJ are estimated

Proceedings of International Conference on Communication Technology. ICCT '96, 2002
A new combined matched-filter serial search PS code acquisition scheme based on surface acoustic wave (SAW) convolver preamble processing is presented in which the correct detection of preambles results in a residual uncertainty of just a few code chips, to be searched sequentially and tracked.

Research on the Method of Using Single-tone Interference to Jam OFDM Signal
2019 IEEE 2nd International Conference on Electronic Information and Communication Technology (ICEICT), 2019The modulation technology of OFDM (Orthogonal Frequency Division Multiplexing) is widely used in high-speed data transmission fields. In order to jam the OFDM communication more effectively, whether the single-tone interference can be used or not and how to set the jamming frequency need to be studied deeply.
