Description: 无线词汇解释1. 香农定理
类比：城市道路上的汽车的车速和什么有关系？和道路的宽度有关系，和自己车的动力有关系，也其他干扰因素有关系（如：车量的多少和红灯的数量）。
香农定理是所有通信制式最基本的原理。 C=Blog2(1＋S/N)： 其中C是可得到的链路速度，B是链路的带宽，S是平均信号功率,N是平均噪声功率，S/N即信噪比。香农定理给出了链
-Wireless glossary 1. Shannon theorem analogy: City of the speed of vehicles on the road and what a relationship? And road width of a relationship, and their own vehicle dynamics, relations, and also other factors that interfere with relationships (such as: how much car traffic and the number of red light). Shannon' s theorem is a basic principle of all communication formats. C = Blog2 (1+ S/N): where C is the available link speed, B is the bandwidth of the link, S is the average signal power, N is the average noise power, S/N or signal to noise ratio. Shannon' s theorem gives the chain Platform: |
