A Design of HDB3 CODEC Based on FPGA
A Design of HDB3 CODEC Based on FPGA

ABSTRACT
The basic principles and structure of HDB3 was briefly introduced in this paper, and the shortcomings of the existing HDB3 encoder and decoder was analyzed. Then a new design of HDB3 encoder and decoder based on FPGA was proposed, and the hardware design circuit and software simulation were introduced. The simulation was achieved through the VERILOG-HDL in EP2C35F672C8 chip of CycloneII series in the development environment of Quartus II 7.2. The results sho ....etc

Abstract

In this paper, a simulation test bed for narrowband Power Line Communications (PLC) is demonstrated. The method is able to quickly assess the performance of modulation schemes for an arbitrary network constructed in the ATP-EMTP software, both for point to point and for multi-point to point communication. Demodulation is carried out in MATLAB. The test setup is used to implement Orthogonal Division Multiplexing (OFDM) on a number of typical medium voltage (MV) distribution networks. The simulation results show that with a considered ....etc

High Density Bipolar Order 3 Encoding

HDB3

The HDB3 code is a bipolar signaling technique (i.e. relies on the transmission of both positive and negative pulses). It is based on Alternate Mark Inversion (AMI), but extends this by inserting violation codes whenever there is a run of 4 or more 0's. This and similar (more complex) codes have replaced AMI in modern distribution networks.

HDB3 Encoding Rules

The encoding rules follow those for AMI, except that a sequence of four consecutive ....etc

Abstract

A new method of combining art image generation and data hiding to enhance the camouflage effect for various information-hiding applications is proposed. First, a new type of computer art, called line-based Cubism-like image, which keeps a characteristic of the Cubism art-abstraction by prominent lines and regions from multiple viewpoints-is proposed. In the creation process with an input source image, prominent line segments in the image are detected and rearranged to form an abstract region-type art image of the Cubism flavor. Data h ....etc
