TLDR
In this article, a design criterion is given to obtain square-root raisedcosine FIR filters with maximum stopband attenuation and low peak distortion, and the filter coefficients can be evaluated easily and the optimal filter parameters can be obtained with tables.Abstract:
A design criterion is given to obtain square-root raisedcosine FIR filters with maximum stopband attenuation and low peak distortion. The filter coefficients can be evaluated easily and the optimal filter parameters can be obtained with tables. The design method is very simple and suited for users not oriented to filter design.read more

Real-time Nyquist pulse generation beyond 100 Gbit/s and its relation to OFDM
Rene Schmogrow,M. Winter,Matthias Meyer,David Hillerkuss,Stefan Wolf,B. Baeuerle,A. Ludwig,Bernd Nebendahl,Shalva Ben-Ezra,J. Meyer,M. Dreschmann,Michael Huebner,Jürgen Becker,Christian Koos,Wolfgang Freude,Juerg Leuthold +15 more
TL;DR: The analogy to optical orthogonal frequency division multiplexing is discussed and it is shown that using appropriate algorithms, Nyquist pulse shaped modulation formats can be encoded on a single wavelength at speeds beyond 100 Gbit/s in real-time.

TL;DR: In this article, the performance of spatial modulation (SM) and spatial multiplexing (SMX) with an experimental testbed is characterized. And the average bit-error ratio (ABER) of the system is validated through both theoretical analysis and simulation results for SM and SMX under the line-of-sight (LoS) channel conditions.

Spatial modulation: theory to practice
TL;DR: A closed–form analytical bound for the ABER performance of SM over correlated and uncorrelated, Rayleigh, Rician and Nakagami–m channels is proposed and it is shown that the proposed sphere decoder algorithms offer an optimal performance, with a significant reduction of the computational complexity.
