Iterative (turbo) soft interference cancellation and decoding for coded CDMA
- IEEE Trans. Commun
, 1999
"... Abstract — The presence of both multiple-access interference (MAI) and intersymbol interference (ISI) constitutes a major impediment to reliable communications in multipath code-division multiple-access (CDMA) channels. In this paper, an iterative receiver structure is proposed for decoding multiuse ..."

computational complexity. A low-complexity SISO multiuser detector is developed based on a novel nonlinear interference suppression technique, which makes use of both soft interference cancellation and instantaneous linear minimum mean-square error filtering. The properties of such a nonlinear interference
Opportunistic Beamforming Using Dumb Antennas
- IEEE Transactions on Information Theory
, 2002
"... Multiuser diversity is a form of diversity inherent in a wireless network, provided by independent time-varying channels across the different users. The diversity benefit is exploited by tracking the channel fluctuations of the users and scheduling transmissions to users when their instantaneous cha ..."

Mitigation of unknown narrowband interference using instantaneous error updates
- 37th Asilomar Conference, 2004
"... Abstract—Nonlinear effects of the Normalized Least Mean Square (NLMS) algorithm are studied in the presence of multipath and severe narrowband interference, for applications where there is no direct reference for the interfering signal. The nonlinear characteristics of the adaptive equalizer are use ..."

are used to generate a reference signal for the interference from the instantaneous error signal. The adaptive coefficients are optimized such that the width of the notch is minimized in order to reduce signal distortion. The bit error rate improvement is quantified as a function of input SINR, multipath
FEATURES OF THE INSTANTANEOUS FREQUENCY ESTIMATION ALGORITHM WITH PRE-FILTERING

The degrees of freedom region and interference alignment for the MIMO interference channel with delayed CSI
, 2011
"... The degrees of freedom (DoF) region of the 2-user multiple-antenna or MIMO (multiple-input, multiple-output) interference channel (IC) is studied under fast fading and the assumption of delayed channel state information (CSI) wherein all terminals know all (or certain) channel matrices perfectly, bu ..."

by developing interference alignment based achievability schemes for each class. A comparison of these DoF regions under the delayed CSI assumption is made with those of the idealistic ‘perfect CSI’ assumption where perfect and instantaneous CSI is available at all terminals on the one hand and with the Do
Timed Concurrent Constraint Programming with Instantaneous Computations
- PROLE
, 2006
"... The timed concurrent constraint programming language (tccp in short), was introduced for modeling reactive systems. This language allows one to model in a very intuitive way typical ingredients of these systems such as timeouts, preemptions, etc. However, there is no natural way for modeling other ..."

desirable features such as functional computations, for example for calculating arithmetic results. In fact, although it is certainly possible to implement such kind of operations, each single step takes time in tccp, and avoiding interferences with the intended overall behavior of the system is quite
Enabling Instantaneous Feedback with Full-duplex Backscatter
"... Abstract – This paper introduces the first design that enables full-duplex communication on battery-free backscatter devices. Specif-ically, it gives receivers a way to provide low-rate feedback to the transmitter on the same frequency as that of the backscatter trans-missions, using neither multipl ..."

and also correct for errors and changes in channel con-ditions at a granularity smaller than that of a packet. To show the feasibility of our design, we build a hardware prototype using off-the-shelf analog components. Our evaluation shows that our design cancels the self-interference down to the noise
Co-Channel Interference Modeling and Analysis in a Poisson Field of Interferers in Wireless Communications
, 2001
"... The paper considers interference in a wireless communication network, caused by users that share the same propagation medium. Under the assumption that the interfering users are spatially Poisson distributed, and under a power-law propagation loss function, it has been shown in the past that the int ..."

that the interference instantaneous amplitude at the receiver is #-stable distributed. Past work has not considered the second-order statistics of the interference, and has relied on the assumption that interference samples are independent. In this paper, we provide analytic expressions for the interference second
Trellis and Convolutional Precoding for Transmitter- Based Interference Presubtraction
"... Abstract—This paper studies the combination of practical trellis and convolution codes with Tomlinson–Harashima precoding (THP) for the presubtraction of multiuser interference that is known at the transmitter but not known at the receiver. It is well known that a straightforward application of THP ..."

that takes into account the knowledge of a noncausal interfering sequence, rather than just the instantaneous interference. At rates of 2 and 3 bits per transmission, trellis shaping is shown to be able to recover almost all of the 1.53-dB shaping loss. At a low SNR, the precoding loss is dominated by power
