经典谱估计，对窗的长度、类型、采样数据长度的影响(The classic spectrum estimation, length, type, the influence of the length of data window sampling)

实现FFT频谱分析，IIR数字滤波器的设计（多种方法），FIR数字滤波器的设计(Implement FFT spectrum analysis, IIR digital filter design (many ways), FIR digital filter design)

Simple Function Approximation

认知中继网络包括一个主用户发射机和接收机，一个次用户发射机和接收机，以及一个放大转发中继。次用户发射机和中继从自然界获取能量。次用户共享主用户的频带进行数据传送，中继放大转发主用户发射机和次用户发射机的信号。次用户发射机和中继根据获取的能量和数据传送要求控制发射功率。功率控制建模为在能量因果约束、(Cognitive relay network includes a primary user transmitter and receiver, a secondary user transmitter and receiver, as well as an amplify and forward relay. Secondary user transmitter and relay obtain energy nature. Secondary users share a frequency band of the primary user data transmission, the relay amplification repeater primary user and a secondary user transmitter the transmitter signal. Secondary user transmitter and a relay and a data transfer request according to the energy obtained by controlling the transmission power. The power control is modeled as a causal constraints in energy,)
