Hard decision spectrum sensing using neural network.

仿真双极性信号通过AWGN信道后的误比特率性能(Simulation bipolar signal bit error rate performance with AWGN channel after。)

matlab code used for face recognition

matlab函数逼近程序，里面包括了常用的matlab函数逼近的程序，包括手写的和matlab自还的函数。(matlab function approximation process, which includes the commonly used matlab function approximation procedures, including hand-written and self is also a function of matlab.)

this is PSO algorithm code that integrated with PID controller. This code example has been used for ASP system.

In sum capacity of an OFDM system is maximized by allocating each subchannel to the user with the highest channel gain over this channel and distributing power among subchannels in a water-filling manner.
