802.11B_wireless_network_card_in_the_implementatio
- 本文是阐述在嵌入式数字信号处理器(DSP)OMAP5912上实现无线网络802.11B的方法。DSP对PC机数据或者直接采样语音信号,通过无线网络传输,实现数据通信。由于系统以DSP为核心,使得无线网络的数字信号处理更加方便,可以较方便地实现数据加密、信号压缩等较复杂的算法。 -This is explained in the embedded digital signal processor (DSP) OMAP5912 802.11B wireless network to realiz
Huffman-coding
- 通信的数字化是它能与计算机技术和数字信号处理技术相结合的基础,而实现通信数字化的前提是信源能提供的各种用于传递的消息,例如语音、图像、数据、文字等都必须以数字化形式表示。而信源编码是数字通信系统中的重要组成部分,他是保证信号有效传输的一种重要方式。霍夫曼编码依据字符出现的概率来构造异字头的平均长度最短的码字,有时称之为最佳编码,其优越的性能被广泛使用在数字通信系统中。霍夫曼编码已经成为数据压缩的灵魂算法。本文介绍了无失真编码算法的构造,霍夫曼编码的规则和特点,同时分析了对信源进行优化的方法,最后
