This paper presents a new family of block codes referred to as Trellis Coded Block (TCB) codes, which are built using a trellis code and a linear block code (LBC). The TCB code (TCBC) construction is based on an algebraic structure inherent to many LBCs, which allows one to partition an LBC into sub-sets with a constant distance between every pair of code words in the subset. The proposed unifo...

The emergence and popularization of various fifth-generation fighter jets with supersonic cruise, super maneuverability, stealth functionalities have raised higher more comprehensive challenges for the tactical performance operational indicators air defense weapon systems. training systems requires simulated targets; however, traditional targets cannot simulate radar cross-section (RCS) distrib...

The feasibility of the application with phase coded waveform to missile borne Millimetre Wave (MMW) Synthetic Aperture Radar (SAR) system was investigated. Based on theory analysis, the geometry model was simplified, the expression of the equivalent range and the Range-Doppler image formation algorithm were deduced simultaneously. The phase coded waveform is pulse compression signal, and it can...

A mutual information inspired nonbinary coded modulation design with non-uniform shaping is proposed. Instead of traditional power of two signal constellation sizes, we design 5-QAM, 7-QAM and 9-QAM constellations, which can be used in adaptive optical networks. The non-uniform shaping and LDPC code rate are jointly considered in the design, which results in a better performance scheme for the ...

Non-intrusive and automatic raw part alignment for machining process is a current challenge for industry, due to the high cost of bad machining. The use of artificial markers, such as coded-targets (CT) provides a promising technique to be applied within industrial environments due to its robustness, non-intrusive nature and low cost. In this paper, an CT identification and decoding algorithm i...

The 3 Dimensional Measuring System is a device to obtain the 3 dimensional coordinates of an object, using its numerous photoimages taken from different angles. This method basically requires the exact identification of the same corresponding points of all the obtained photo-images. But the more numerous are the images, the longer and harder it becomes if we depend on the manual work. To solve ...
