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 ...

The Serial Concatenation of Rate-1 Codes Through Uniform Interleavers [PDF]

open access: yes, 2003
Introduction Since the introduction of turbo codes by Berrou, Glavieux, and Thitimajshima [3], iterative decoding has made it practical to consider a myriad of different concatenated codes, and the use of "random" interleavers and recursive ...

Convolutional Coupled Codes [PDF]

open access: yes, 2003
This thesis is about convolutional coupled codes - codes constructed via concatenation of several outer systematic convolutional encoders and several inner systematic block encoders linked by divers interleavers. The code is nonsystematic, since only the

Blind Identification of Block Interleaved Convolution Code Parameters

open access: yesDefence Science Journal, 2019
Most of the digital communication system uses forward error correction (FEC) in addition with interleaver to achieve reliable communication over a noisy channel. To get useful information from intercepted data, in non-cooperative context, it is necessary to have algoritihms for blind identification of FEC code and interleaver parameters. In this paper,

Enhancement Methods of High-Performance Interleavers for Turbo Codes [PDF]

open access: yes, 2012
[[abstract]]渦輪碼是一個擁有極佳錯誤更正能力的通道編碼技術,現今也已成為第四代行動通訊-長期演進技術(Long Term Evolution LTE)的標準之一。渦輪碼是由兩個旋積碼(Convolutional Code)經由一個交錯器(Interleaver)並聯串接而成。交錯器的主要功能在於將傳送至第一旋積碼的資料序列重新排列成另一個新的資料序列以做為第二旋積碼的輸入資料。而交錯器的排列順序已被證實是決定渦輪碼性能的一個最重要關鍵因素。如何設計出最佳交錯器至今仍是一個有待解決的議題 ...

EXIT charts for system design and analysis [PDF]

open access: yes
Near-capacity performance may be achieved with the aid of iterative decoding, where extrinsic soft information is exchanged between the constituent decoders in order to improve the attainable system performance.
