In a normal communication channel, it is often desirable to concentrate the information in as narrow a region of the frequency spectrum as possible in order to conserve available bandwidth and to reduce power. The basic spread spectrum technique, on the other hand, is designed to encode a stream of information by spreading the encoded data across as much of the frequency spectrum as possible. This allows the signal reception, even if there is interference on some frequencies. While there are many variations on spread spectrum communication, we concentrated on Direct Sequence Spread Spectrum encoding (DSSS). The DSSS method spreads the signal by multiplying it by a chip, a maximal length pseudorandom sequence modulated at a known rate. Since the host signals are in discrete-time format, we can use the sampling rate as the chip rate for coding.

多组处理，仅展开一个区块的折叠效果(原生Js和jQuery版)，俗称“手风琴菜单”，习惯叫做折叠菜单，一个页面中布置了多组菜单，部分代码释义如下： 　　var navItem=iBase.Id(‘demo‘).getElementsByTagName(‘h2‘) //此处将jQ区块中的h2也取到了,所以页面会有个小小的错误 (Multiple sets of treatment, only one block to start folding effect (native Js and jQuery version), commonly known as accordion menus , used to be called folding menu, a page layout of the multiple sets of menus, the interpretation of the code is as follows: var navItem = iBase.Id ( demo ) getElementsByTagName ( h2 ) . // Here jQ block will also take to the h2, so the page will have a small mistake)
