Interference suppression in ultrawideband communications

by Li Zhao, Er M. Haimovich - in Proc. 35th Annual Conf. Inform. Sci. and Syst
"... Abstract | In this paper we analyze the perfor-mance of ultra-wideband (UWB) communications in the presence interference. The interference is mod-eled as a zero mean random process with constant power spectral density over a certain bandwidth. Mathematical expressions are developed for the jam resis ..."

resistance of a pulse position modulation UWB utiliz-ing a Gaussian monocycle. We also compare the inter-ference suppression properties of UWB with those of direct-sequence spread spectrum (DS-SS). It is shown that under certain assumptions UWB provides more eective interference suppression than DS-SS. I.

Interference Mitigation in Frequency-Hopped Spread-Spectrum Systems

by Andrew Worthen And, Wayne Stark - in Proceedings of the IEEE 6th International Symposium on Spread-Spectrum Techniques and Applications ISSSTA’00 , 2000
"... In this paper we explore the error probability of different coding schemes in a frequencyhopped spread-spectrum communication systems subject to partial-band interference and a system subject to Rayleigh fading. The interplay between block length of the code and channel memory is quantified. We show ..."

Narrowband Interference Suppression in Spread Spectrum CDMA

by H. Vincent Poor, Leslie A. Rusch , 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, ..."

-based 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

Spread Spectrum Interference Suppression Using Adaptive

by Time-Frequency Tilings Brian, Brian S. Krongold, Michael L. Kramer, Kannan Ramchandran, Douglas L. Jones , 1997
"... Interference suppression in spread spectrum communication systems is often essential for achieving maximum system performance. Existing interference suppression methods do not perform well for most types of nonstationary interference. We first consider interference suppression schemes based on adapt ..."

Suppression of Multiple Narrowband Interferers in a Spread-spectrum Communication System

by C. Carlemalm, H.V. Poor, A. Logothetis - IEEE J. Select. Areas Commun , 2000
"... We consider the problem of estimating and suppressing many unknown independent and time-varying interferers in a spread-spectrum communication system. The interferers are assumed to be present in a wide frequency range. In order to detect, estimate and track the interference, we use a bank of hidden ..."

Decorrelator Based Narrowband Interference Suppression in Spread Spectrum Communications

by Youngkwon Cho, Student Member, Jae Hong Lee
"... Abstract- In this paper, multiuser detectors for a synchro-nous code division multiple access (CDMA) channel are adopted for detecting a spread spectrum signal in the pres-ence of a digitally modulated narrowband interference (NBI). The bit error probability of a decorrelating detector is independen ..."

Performance of Reed-Solomon Coded Frequency-Hop Spread-Spectrum Communications in Partial-Band Interference

by Michael B. Pursley, Wayne, Wayne E. Stark - IEEE Trans. Commun , 1985
"... This paper is concerned With the performance of a Commun- ications system which utilizes frequency-hop spread spectrum, diversity transmission, Reed-Solomon coding, and parallel error-correction and erasure-correctiOn decoding. Both binary signaling and M-ary orthogonal signaling are considered. The ..."
