UWB interference to narrowband receivers
CCNC 2006. 2006 3rd IEEE Consumer Communications and Networking Conference, 2006., 2006This paper studies the in-band interference of timehopping spread spectrum (TH-SS) UWB signals to narrow band receivers. Based on the analysis of general power spectral density (PSD) of TH-SS UWB signal, the interference of UWB signal can be partitioned into two parts: (1) additive white Gaussian noise interference (2) jamming tone interference ...

The Effects of Narrowband Interference on OCDM
2020 IEEE 21st International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2020Orthogonal chirp division multiplexing (OCDM) is a fairly new multi-carrier modulation scheme that has been proposed for optical fiber communications. It spreads data over an entire band using a set of linear chirps that are mutually orthogonal thus achieving the maximum spectral efficiency. This paper analyzes the performance of OCDM in wireless multi-

Improvement of the narrowband LPC synthesis
ICASSP '84. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005The major weakness of the current narrowband LPC synthesizer lies in the use of a "canned" invariant excitation signal. The use of such an excitation signal is based on three primary assumptions, namely, (1) that the amplitude spectrum of the excitation signal is flat and time-invariant, (2) that the phase spectrum of the voiced excitation signal is a ...

Detection of known Narrowband Signals in Narrowband Noise
1988In the last three chapters we have been concerned with the detection of known signals which may be characterized as being low-pass signals. We did not put any explicit constraints on the known signal values s i , but required the noise components W i to be independent for i = 1,2,…,n. When the data are generated as samples of some continuous-time input

Narrowband chemical-shift imaging
Applied Optics, 1985In this paper we introduce an efficient method for NMR chemical shift imaging which is especially well suited for imaging proton chemical shifts. With realistic observation times and pulse sequences, one is operating close to the theoretical limits of this method.

Narrowband cooperative network localization
2014 IEEE Global Communications Conference, 2014We consider the problem of distributed cooperative location estimation in motionless and mobile narrowband wireless sensor networks (WSNs), where network terminals (to be localized) are several hops away from the anchor nodes (with a priori known location).

Narrowband fiber grating filters
IEEE Journal on Selected Areas in Communications, 1990Two techniques for the fabrication of fiber gratings with a narrowband filter response are reported. In the first technique, the reflection bandwidth is reduced by increasing the grating length. Fiber gratings 10 mm long have been made with a bandwidth of approximately 0.3 nm.

Journal of the Canadian Association of Radiologists, 1983
A narrowband communication system using the Canadian satellite ANIK-B was used to transmit radiographic images from northern Quebec to Montreal. This slow scan television (SSTV) system was used to study the accuracy of the radiologist's interpretation, both with samples of pre-selected films and current patients.

Fast estimation of narrowband spectra
ICASSP '79. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005A new method is investigated for a fast and consistent estimation of the spectral density of stationary processes which are narrowband. The method exploits the Toeplitz structure of the classical smoothed periodogram estimates and their similarity to circulant forms.
