算术编码在图象数据压缩标准（如jpeg，jbig）中扮演了重要的角色。在算术编码中，消息用0到1之间的实数进行编码。算术编码用到了两个基本的参数：符号的概率和它的编码间隔。信源符号的概率决定压缩编码的效率，也决定编码过程中信源符号的间隔，而这些间隔包含在0到1之间。编码过程中的间隔决定了符号压缩后的输出。-Arithmetic Coding

由于音像制品的品种繁多,所以音像租赁对于数据的查找,修改,删除和添加等功能的需求量很大,用人工手记的方式显然很烦琐,所以本项目就是为此设计.本项目可以对音像制品进行规范化管理,进而提高经营效率,实现中小音像租赁店日常工作的管理.-as audio and video products, the wide variety and audio data for the lease to search, modify, delete and add features such as the high demand for use of artificial Notes obviously very cumbersome, so this is the project design. This item can be audio-video products for regulation and then mention the high operating efficiency, small and medium-sized audio-video rental shops daily work management.

ofdm仿真
说明： OFDM即正交频分复用技术，多载波调制的一种。其主要思想是：将信道分成若干正交子信道，将高速数据信号转换成并行的低速子数据流，调制到在每个子信道上进行传输。。每个子信道上的信号带宽小于信道的相关带宽，因此每个子信道上的可以看成平坦性衰落，从而可以消除符号间干扰。而且由于每个子信道的带宽仅仅是原信道带宽的一小部分，信道均衡变得相对容易。(Orthogonal Frequency Division Multiplexing (OFDM) is a kind of multi-carrier modulation. The main idea is to divide the channel into several orthogonal sub-channels, convert high-speed data signals into parallel low-speed sub-data streams, and modulate them to transmit on each sub-channel. The signal bandwidth on each sub-channel is less than the correlation bandwidth of the channel, so it can be seen as flat fading on each sub-channel, which can eliminate inter-symbol interference. Moreover, since the bandwidth of each subchannel is only a small part of the original channel bandwidth, channel equalization becomes relatively easy.)
