Manufacturing an Erasure Wiretap Channel from Channel Sounding Measurements

2019 IEEE International Symposium on Information Theory (ISIT), 2019
In this paper we provide a real-world test of physical-layer security using channel sounding techniques in an indoor wireless network. We consider the possibility of exploiting issues that arise in practical receivers to manufacture a discrete memoryless wiretap channel model from the Gaussian case, and show how the secrecy capacity of the Gaussian ...

Weak NLOS channel sounding

2006 European Microwave Conference, 2006
A novel approach using differential reception and nulling interferometry is devoted to weak Non Line Of Sight (NLOS) signals measurement. Performed either in the spatial domain or in the spectral domain, this method can achieve Line Of Sight (LOS) dimming, and then NLOS emphasis.

Underwater Sound Channel

1982
The underwater sound channel (USC) is a typical natural waveguide. The types of ocean stratification leading to the formation of an USC have been given in Sect. 1.2. The theory of sound propagation in the USC is presented here.

Sound channels in the atmosphere

Journal of Geophysical Research, 1963
The mean temperature profile of the atmosphere indicates the probable existence of two horizontally distributed sound waveguides in the atmosphere. The lower one usually occurs between the surface and 50 km, and the upper between 50 and 110 km. Wind data above 30 km, which have become available recently through the use of meteorological rockets, have ...

Compressive spatial channel sounding

12th European Conference on Antennas and Propagation (EuCAP 2018), 2018
In this paper we investigate the application of Compressed Sensing (CS) to MIMO channel sounding in the spatial domain. A compressive spatial channel sounder is proposed and evaluated based on real scenarios showing advantages in terms of time, hardware complexity and resolution.

Method and Apparatus to Simulate 2-Channel Virtualized Sound for Multi-Channel Sound

The Journal of the Acoustical Society of America, 2011
A stereo sound generation method and apparatus to generate a stereo sound, by using 2-channel headphones, earphones, or speakers, from a multi-channel sound signal reproduced through a variety of media such as a DVD-video, and a DVD-audio. The stereo sound generation method of generating a 2-channel stereo sound from a 5.1-channel sound signal includes:

Channel sounding realizations for indoor wireless communication

2015 23nd Signal Processing and Communications Applications Conference (SIU), 2015
In this paper, a realization of an FFT based channel sounding technique and resulting channel functions depending on time, frequency and delay are presented. Practical measurements and computer simulations can provide useful information for wireless communication system designs.

On the use of sounding in wideband channels

2006 International Zurich Seminar on Communications, 2006
In wideband channels, the energy per degree of freedom does not suffice to provide an accurate measurement of the channel over the entire spectrum. However, in the presence of feedback, we may garner information at the sender about some aspects of the channel quality over certain portion of the spectrum.

Plural-channel sound processing

The Journal of the Acoustical Society of America, 1998
An artificial head (2) and a plurality of discrete monophonic microphones (8, 10, 12) are used to record one or more sound sources. The signals (14, 16, 18) from each of the microphones (8, 10, 12) then undergo binaural synthesis based upon acoustical properties of a real human head or the artificial head (2), and the signals (4, 6) from the head are ...
