A code-aided technique for the simultaneous suppression of narrow-band interference (NBI) and multiple-access interference (MAI) in direct-sequence code-division multiple-access (DS/CDMA) networks is proposed. This technique is based on the linear minimum mean-square error (MMSE) algorithm for multiuser detection.

Interference Suppression in Synthesized SAR Images
IEEE Geoscience and Remote Sensing Letters, 2005Radio interferences are becoming more and more an important source for image degradation in synthetic aperture radar (SAR) imaging. Especially at longer wavelengths, interferences are often very strong, and their suppression is required during data processing.

Multipath Interference Suppression
2017Interferences on GNSS can be categorized into two types: intentional interference and unintentional interference. Jamming and spoofing, mainly discussed in Chaps. 2 and 4 in this book, belong to the category of intentional interference. Multipath interference studied in this chapter, and pulse interference that will be studied in Chap. 6 both belong to

Enhanced interference whitening for co-channel interference suppression
2013 IEEE Wireless Communications and Networking Conference (WCNC), 2013The co-channel interference (CCI) has become a major throughput-limiting factor for cell-edge users in the modern cellular systems such as the Long Term Evolution (LTE) network. Spatial interference whitening (IW) is an effective low-complexity linear method to suppress colored spatial interference in a MIMO setup.

Residual interference suppression in parallel interference cancellation receivers
1999 IEEE International Conference on Communications (Cat. No. 99CH36311), 2003Parallel interference cancellation (PIC) receivers are among the most promising receiver techniques for future code-division multiple-access (CDMA) systems. Interference cancellation efficiency relies on the knowledge of the number of users and propagation paths needed in multiple-access interference (MAI) estimation.

Pulse Interference Suppression Techniques
2017Intentional interferences mainly include multipath interference and pulse interference. We studied multipath interference in the last chapter. In this chapter we study the suppression of the other type of intentional interference—the pulse interference.

Interference suppression of SRS
Quantum Electronics, 2011The theory of three-wave SRS is developed, which takes into account nonlinear dispersion of a medium for arbitrary phases of the pump waves at the input to the medium. The effect of interference suppression of SRS is predicted for values of the total phase of the three-wave pump (2n+1)π (n=0, ±1, ±2...), the effect being caused by the destructive ...

Suppressing QPSK DS/CDMA interference
Proceedings of ISSSTA'95 International Symposium on Spread Spectrum Techniques and Applications, 2002Three adaptive QPSK direct-sequence code-division multiple-access (DS/CDMA) receivers for suppressing QPSK DS/CDMA interference are introduced. Performance results for the three proposed receivers, as well as results for the linear correlation receiver, are provided.

Interference suppression for DS/CDMA
IEEE Transactions on Communications, 1999A direct-sequence spread spectrum (DS/SS) receiver for suppressing multiple-access interference in direct-sequence code-division multiple-access (DS/CDMA) communication systems is introduced. The proposed receiver does not require knowledge of other users' spreading codes, timing, or phase information.

Fat suppression by echo interference
Magma: Magnetic Resonance Materials in Physics, Biology, and Medicine, 1994Two spectral components of a binary system, like water and fat in proton magnetic resonance imaging (MRI) can be separated by adding two signals acquired with a different delay (the Dixon method). The same effect can be obtained in a single acquisition by interference of two shifted echoes.
