CPFSK
该工程是有关CPFSK（连续相位调制）的完整工程。帧结构包含训练序列、前导码、同步码、数据长度等信息，使用正交调制方式产生CPFSK的信号，生成基带IQ数据。接收端包含帧同步、滤波、解算长度等算法。可实现任意长度字符串的无线发送与接收。工程十分完整喝强大，可直接用于各大SDR平台的验证。(The project is a complete project of CPFSK (continuous phase modulation). The frame structure contains training sequence, preamble, synchronization code, data length and other information, and uses orthogonal modulation to generate CPFSK signals and generate baseband IQ data. The receiver includes algorithms such as frame synchronization, filtering, and calculating length. It can realize wireless sending and receiving strings of arbitrary length. The project is complete and powerful, and can be directly applied to the verification of major SDR platforms.)

Doppler-spectrum-of-radio-channel
1. 关于无线信道的多普勒谱，请回答以下问题：
(1) 在某些无线信道中，多普勒频移会引起无线信道输出信号的混叠。请清楚的描述产生混叠的各种原因；
(2) 无线信道中的多普勒谱有一种经典谱(classic spectrum)，请解释产生这种谱形状的机理；
(3) 请用S-function产生一单径瑞利信道，其多普勒谱为经典谱，其中移动速率为120km/h。并请回答：证明自己用计算机产生的经典谱是正确的可能方法。
