：主要介绍m序列、Gold序列、Kasami序列和JPL序列的生成原理及其MATLAB的实现，并介绍如何用MATLAB中 Simullnk对其进行硬件仿真，给出了相应自相关和互相关结果。(: The main introduction m sequence, Gold sequences, Kasami sequences and sequences generated JPL principle and the realization of MATLAB, and introduce how to use MATLAB in their Simullnk hardware simulation, the corresponding auto-correlation and cross-correlation results.)

This code applies local histogram equalization on an input image with a view to improve its contrast ratio. The image is read, converted to grayscale and resized with the inbuilt function of MATLAB. The window size may be changed, however, the window shift is as per size of the window. The output is definitely a better contrast image as compared to the input but checkerboard effect is evident.

The objective of this paper is to provide a road map to understanding and use of real-time design patterns. To meet this objective, we provide a brief overview of the origins of design patterns, then discuss a wide variety of specific real-time design patterns, and finally provide our own classification of patterns, which is derived from a systematic approach to real-time system design and real -time software architectures.
