Turbo Codes Performance Optimization over Block Fading Channels

open access: yesJournal of Communications Software and Systems, 2006
In this paper, the best achievable performance of a turbo coded system on a block fading channel is obtained, assuming binary antipodal modulation. A rate 1/3 turbo code is considered, obtained by concatenating, through a random interleaver, an 8-states ...

A Fast Rotation Detection Network with Parallel Interleaved Convolutional Kernels

open access: yesSymmetry
In recent years, convolutional neural network-based object detectors have achieved extensive applications in remote sensing (RS) image interpretation. While multi-scale feature modeling optimization remains a persistent research focus, existing methods frequently overlook the symmetrical balance between feature granularity and morphological diversity ...

Performance of convolutional interleavers with different spacing parameters in turbo codes [PDF]

open access: yes, 2005
This paper considers application of a convolutional interleaver and the issue of influence of the space parameter in the turbo code performance. Similarly to previously considered convolutional interleavers, the new interleavers are designed as block ...

Interleaver design for trellis-coded differential 8-PSK modulation with non-coherent detection [PDF]

open access: yes, 1988
The effect of finite interleaver size on bit error rate (BER) performance of coded 8-DPSK is determined by means of computer simulations. The losses evaluated in this way include the SNR degradation due to the timing and frequency errors of the symbol ...
