Poisson-s-Equation

本文主要是描述的DDC的matlab功能，从输入的信号经过1/4fs搬频，然后半带抽取，再到混频，最后到分数倍的抽取，再经过成形滤波器输出。(digital down convention)

pattern generator for pattern recognition

这是一个相对完整的OFDM通信系统的仿真设计，包括编码，调制，IFFT，上下变频，高斯信道建模，FFT，PAPR抑制，各种同步，解调和解码等模块，并统括系统性能的仿真验证了系统设计的可靠性。 (This is a relatively complete simulation of OFDM systems design, including coding, modulation, IFFT, up and down conversion, Gaussian channel model, FFT, PAPR suppression of synchronization, demodulation and decoding modules, and systems, including system performance simulation verifies the reliability of system design.)
