Fundamental Applicability of Spatial Modulation: High-SNR Limitation and Low-SNR Advantage

IEEE Journal on Selected Areas in Communications, 2019
Spatial modulation (SM) is viewed as a promising multi-antenna technology for future communications. Numerous works on SM have been done on the specific optimized designs and performance analysis mainly based on high signal-to-noise ratio (SNR) union bound approximation.

Transmitter SNR for Maximum Coverage

IEEE Transactions on Broadcasting, 2008
The generally accepted notion that DTV coverage will not be materially improved if the transmitter's SNR were raised from 27 dB to 32 dB is shown to be true only for perfect links. In real world links a significant improvement in coverage would materialize.

A reduced complexity SNR estimator

IET Conference Publications, 2009
This paper presents a novel reduced complexity SNR estimator, whose performances are comparable with the maximum-likelihood estimator while saving one half of the floating point multiplications and one third of the floating point sums. A detailed statistical description of the estimate, as well as simulation results, are provided. (4 pages)

SNR-Based Link Quality Estimation

2012 IEEE 75th Vehicular Technology Conference (VTC Spring), 2012
The ability to accurately estimate wireless link quality is critical to the performance of routing protocols and rate adaptation algorithms in wireless mesh networks. Current link quality estimation methods utilize the packet delivery ratio (PDR) measurement of periodic broadcast probes sent at the lowest transmission rate.

The SNR Threshold in PPM Reception

IEEE Transactions on Communications, 1974
The signal-to-noise-ratio (SNR) performance of a pulse-position-modulation (PPM) receiver is well understood when the input SNR exceeds the threshold, but below it the output SNR deteriorates on account of false pulses due to noise. The calculation of their effect, which determines the threshold, has been considered a difficult problem.

Photoionising Shocks in SNRS and AGN

Astrophysics and Space Science, 1995
A high velocity radiative shock, or one moving into high-metallicity gas, provides an efficient means to generate a strong local UV photon field. The optical emission from the shock and precursor region is dominated by the photoionised gas, rather than by the cooling region, and the total optical + UV emission scales as the mechanical energy flux ...
