- Physically, a channel can be a frequency band(under FDMA), or an orthogonal code(under CDMA).Then, there is no interference between two routes. 通过一次路由发现,获得两条节点不相交路径,按照每包分配策略,把数据交替在两个信道的不同路径上进行传输。
- One way to solve above problem is to enhance the frequency spectrum using efficiency, then CDMA use different code sequence in each channel, and uses the orthogonal code sequence to make the channel orthogonal. 解决上述矛盾的一种途径是提高频谱的有效利用率,而码分多址(CDMA)则是在每个信道使用不同的码序列,并且使用相互正交的码序列来实现信道的正交,这样由不同的码序列来区分不同的用户的方法将很好的解决频带共享的问题,提高了频带利用率。
- In optical code division multiple access system, the length of optical orthogonal code (OOC) should be in creased in order to improve system capacity and thus to compress optical pulses. 摘要在光码分多址系统中,提高系统容量需要增大光正交码的长度,从而压缩光脉冲,而超短光脉冲的产生不易实现。
