Design of a Modified Interleaving Algorithm Based on Golden Section Theory Enhancing the Performance of Turbo Codes

Essedik Iftene, Adda Ali-Pacha, Lahcene Hadj Abderrahmane
2022 Journal of Telecommunications and Information Technology  
The performance of the proposed interleaving method is compared with that of matrix (M), random (R), and dithered golden (DG) interleavers.  ...  Results of simulations performed both in the additive white Gaussian noise (AWGN) channel and the Rayleigh fading channel demonstrate the effectiveness of the proposed interleaver.  ...  BER and FER performance comparison between interleavers in the Rayleigh channel: (a) frame length N = 400 and (b) frame length N = 1024.  ...

Space-Time Coding: an Overview

Giuseppe Caire, Petros Elia, K. Raj Kumar
2017 Journal of Communications Software and Systems  
The code design for the quasi-static, outage limited, fading channel is recognized as the most challenging and innovative with respect to traditional "Gaussian" coding.  ...  This culminates with the description of families of codes that are optimal with respect to the DMT criterion and have error performance that is very close to the information theoretic limits.  ...  Fig. 6 shows a comparison between the Golden code and the Gosset S-LAST code (obtained by taking Λ ′ to be the Gosset E 8 lattice in 8 dimensions) under ML and MMSE-DFE Lattice Decoding.  ...

Tip-enhanced near-field optical microscopy [article]

Corneliu Catalin Neacsu, Humboldt-Universität Zu Berlin, Humboldt-Universität Zu Berlin
2017
As a partially asymmetric nanostructure, the tip allows for the clear distinction of local surface and nonlocal bulk contributions to the nonlinear polarization and the analysis of their polarization and  ...  The plasmonic character of Au tips is identified and its importance for the optical tip-sample coupling and subsequent near-field confinement are discussed.  ...  Thus, dithering the tip and taking the difference between the optical signal close and far from the sample a much better filtering of the near-field SHG is achieved.  ...

The resources required to achieve this additional science are outside of what is currently budgeted for LSST by NSF and DOE, and for WFIRST (or Euclid) by NASA.  ...  Funding for this science would most naturally emerge from coordination among all agencies involved, and would be closely orchestrated scientifically and programmatically to optimize science returns.  ...  Early interface testing between the observatory and ground system is performed to verify performance and mitigate risks to launch readiness.  ...
