Rayleigh-fading-channel

introduction to power electronics and its applications

非常经典的软件射频通用处理和设计，麻省理工学院计算机系的博士们写的(A very classic Universal software radio processing and design, Department of Computer Science Massachusetts Institute of Technology who wrote a doctoral)

Spread spectrum techniques can be very useful to overcome the communication problems like security and efficient usage of power. In this technique, the information signal to be transmitted is multiplied by the PN code (This is the general case and it can be any kind of sequence.),called spreading code signal. The signal which is obtained after the multiplication of PN code is called spread signal which is then transmitted.

This code calculate the Qam modulation for a network communication
