A fixed compression dictionary is created to change the fact that an image has one-to-one compression dictionary and advance the application of the Mandelbrot image in fractal image compression algorithm.

A steady dictionary is constructed to change the fact that an image has only one compression dictionary.

Fractal image compression dictionary is a key factor in the realiation of fractal image compression coding, and the main defect of traditional fractal image compression dictionary coding designed by Barnsley is that the compression dictionary is very small.

FPGA Implementation for the Digital Pulse Compression and CFAR Detector;

Based on technique of digital orthogonal detection and digital pulse compression,a design of a digital IF receiver is introduced in this paper,which is based on FPGA IP core and can be used for DDC and some preprocessing of chirp signal.

The specific transfer process is:when images sent by the television and sound signals,after digital compression and digital modulation,and formation of digital television signals,then via the satellite,and broadcasting or cable transmission,then the digital television receivers,solute and reconcile the figures as the audio decoder to deal with to restore the original images and sound.

In this paper a method of Chinese font compression is created by using cubic B_spline wavelet transformation.
