Interference Management versus Interference Cancellation: SATCOM Case

2011
Interference management and interference cancellation are addressed in the satellite communication (SATCOM) system. We first introduce the two options for a multibeam payload: flexible (FLEX) where allocation is fully flexible in the frequency domain, and conventional on which beamforming (BF) is applied. Further, two optimization problems are proposed,

Wideband Interference Cancellation in Adaptive Sidelobe Cancellers

IEEE Transactions on Aerospace and Electronic Systems, 1983
This paper presents numerical results from a study of sidelobe cancellers operating against wideband interfering signals. The study was designed to provide information that would be useful to system designers. Among other things, we address the question of whether it is best to enhance the bandwidth capability of the canceller by using tapped delay ...

Equalization and Interference Cancelation

2011
This chapter concentrates on the modeling of intersymbol interference (ISI) channels and the various signal processing methods for recovering digital information transmitted over such channels. The chapter begins with a treatment of ISI channel modeling, including a vector representation of digital signaling on ISI channels. We then develop the maximum

A Method of Cancellation Interference in CCFD System

2018
Co-frequency Co-time Full Duplex (CCFD) is a key concept brought up in 5G, of which the key technology is self-interference (SI) cancellation. Among all the cancellation technology, the digital cancellation technology has the advantage of being flexible and efficient, and further improving its performance is an important way to reduce the cost, power ...

Transmit Diversity Based Interference Cancellation

VTC Spring 2008 - IEEE Vehicular Technology Conference, 2008
In this paper, we describe a transmit diversity technique for canceling partially-known interference. For a single interferer in a flat fading channel, the desired user transmitter transmits conjugated and time-reversed interferer symbols in two successive symbol periods (or subcarriers) along with one desired user symbol.

Beyond digital interference cancellation.

2010
One of the major drawbacks towards the realization of MIMO and multi-sensor wireless communication systems is that multiple antennas at the receiver each have their own separate radio frequency (RF) front ends and analog to digital converter (ADC) units, leading to increased circuit size and power consumption.
