无论是军事通信领域,还是商用通信领域,扩频通信技术都扮演着极其重要的角色。为了达到将数据比特扩频的目的,通常的做法是用一扩频码序列与待发射的信号相乘,从而扩频序列具有比信息数据宽很多的频带。本文是基于LZW算法对一组64位m序列压缩与解压通信传输。相比Huffman算法,采用LZW编码算法对m序列进行数据压缩,可以获得更高的数据压缩比,从而减少了传输带宽以及占用空间少,速度快的目的。
Spread spectrum communication technology plays an extremely important role both in the field of military communications and in commercial communications. In order to spread the data bits, it is common practice to multiply the signal to be transmitted by a spreading code sequence so that the spreading sequence has a much wider band than the information data. This paper is based on LZW algorithm for a 64-bit m sequence compression and decompression communication transmission. Compared with the Huffman algorithm, the LZW encoding algorithm is used to compress the data of the m sequence to obtain a higher data compression ratio, thereby reducing the transmission bandwidth, less occupied space and fast speed.
