Generalised clarke model for mobile-radio reception
Clarke’s classical model of mobile radio reception assumes isotropic rich scattering around the mobile receiver antenna. The assumption of isotropic scattering is valid only in limited circumstances. In this contribution we develop a generalized Clarke model, which is applicable to mobile radio reception in general scattering environments. We give expressions for the autocorrelation and power s...
متن کاملTransmission and Reception Front-End Algorithms for Software Defined Radio
We present low-complexity algorithms for transmitter and receiver front-end suited to the implementation of software defined radio (SDR) terminals. The proposed algorithms make the processing sampling frequency independent of the symbol rate of the digitally modulated signal and use the “IF-sampling” technique for D/A and A/D conversion. As a case-study, we consider a training-based joint multi...
متن کاملIx. Solar Radio Emission
The emission of solar flares at millimeter wavelengths is of great interest both in its own right and because it is generated by the energetic electrons which also emit gamma rays. Since high-resolution imaging at gamma-ray energies is not presently possible, millimeter observations can act as a substitute. Except for that class of flares known as gamma-ray flares the millimetric emission is op...
متن کاملSolar Radio Bursts and Space Weather
Space Weather is the study of the conditions in the solar wind that can affect life on the surface of the Earth, particularly the increasingly technologically sophisticated devices that are part of modern life. Solar radio observations are relevant to such phenomena because they generally originate as events in the solar atmosphere, including flares, coronal mass ejections and shocks, that prod...
متن کاملRadio-Activity
In a previous paper* Fr. Sierp and myself have dealt with some of the numerous hot springs in the Bombay Presidency. The favourable reception which that paper has received relieves me of the necessity of dwelling once more on the importance of the subject. The methods used in the present paper in measuring the radio-activity of the water and the gases are the same as in the former investigation...
