Cognitive Radio: Brain-Empowered Wireless Communications
, 2005
"... Cognitive radio is viewed as a novel approach for improving the utilization of a precious natural resource: the radio electromagnetic spectrum. The cognitive radio, built on a software-defined radio, is defined as an intelligent wireless communication system that is aware of its environment and use ..."

Implementation issues in spectrum sensing for cognitive radios
- in Proc. the 38th. Asilomar Conference on Signals, Systems, and Computers
, 2004
"... Abstract- There are new system implementation challenges involved in the design of cognitive radios, which have both the ability to sense the spectral environment and the flexibility to adapt transmission parameters to maximize system capacity while co-existing with legacy wireless networks. The cri ..."

Narrowband Interference Suppression in Spread Spectrum CDMA
, 1994
"... this paper is to provide an overview of these techniques. An excellent review of those methods developed prior to 1988 can be found in a survey paper authored by Milstein [12]. Thus, although we will review all of the methods that have been proposed, we will treat these earlier methods only briefly, ..."

techniques that employ non-standard signal processing methods to enhance the interference rejection capabilities in CDMA systems beyond those of standard methods. In particular, in the second section we consider techniques based on nonlinear filtering [15] in which the spread spectrum CDMA signal (which
Fading Channels: Information-Theoretic And Communications Aspects
- IEEE TRANSACTIONS ON INFORMATION THEORY
, 1998
"... In this paper we review the most peculiar and interesting information-theoretic and communications features of fading channels. We first describe the statistical models of fading channels which are frequently used in the analysis and design of communication systems. Next, we focus on the information ..."

Narrowband Interference Suppression in Wireless OFDM Systems
"... Abstract—Signal distortions in communication systems occur between the transmitter and the receiver; these distortions normally cause bit errors at the receiver. In addition interference by other signals may add to the deterioration in performance of the communication link. In order to achieve relia ..."

Research Article Other-Cell Interference Reducing Resource Allocation in OFDM-Based Asynchronous Cellular Systems
, 2007
"... Orthogonal frequency division multiplexing (OFDM) is considered as one of the most promising techniques for next-generation wireless access systems. However, it may suffer from the so-called other-cell interference (OCI) in cellular environments. In this paper, we consider a novel resource allocatio ..."
