The measurement and suppression of radio interference

Journal of the British Institution of Radio Engineers, 1949
The paper firstly outlines the nature of Radio Interference and the principles of measurement, goes on to describe measurement techniques as used by a manufacturer, and briefly reviews available methods of suppression and the difficulties encountered in their application.

Code-aided interference suppression for DS/CDMA communications. I. Interference suppression capability

IEEE Transactions on Communications, 1997
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.

Suppression of Strong Interference in UWB

2011 IEEE Global Telecommunications Conference - GLOBECOM 2011, 2011
The large bandwidth and low power level of ultra- wide-band make it susceptible to interference. Especially in a cell phone the interference levels are very high. Therefore cell phone integration of UWB receivers requires strong interference suppression. In this paper we use realistic models of interferers present in a cell phone. These models are used

A novel adaptive filter for interference suppression

2013 IEEE International Conference of IEEE Region 10 (TENCON 2013), 2013
In wireless communication systems of consumer electronics, it is very important to suppress the interference and extract the target effectively without any phase-amplitude shift. A number of signal processing optimal algorithms developed, we apply the smart antenna to adaptive filtering. But the performances of adaptive filtering differ from each other

Pulse Interference Suppression Techniques

2017
Intentional 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.

Enhanced interference whitening for co-channel interference suppression

2013 IEEE Wireless Communications and Networking Conference (WCNC), 2013
The 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), 2003
Parallel 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.

Cochannel Talker Interference Suppression

1991
Abstract : Cochannel talker interference suppression is defined as the processing of a waveform containing two simultaneous speech signals, referred to as the target and the jammer, to produce a signal containing an estimate of the target speech signal alone.

Radio Frequency Interference Suppression

2011
Section 3.8 presented the problem of the radio frequency interference (RFI) environment in ultra wideband (UWB) radar operation from the standpoint of background clutter. This chapter will cover the significant design factors needed to operate a foliage penetration (FOPEN) radar, in either synthetic aperture radar (SAR) or ground moving target ...
