This program includes serial communication, Tetris, scientific calculator, password login box, ERNIE station matlab program can be run directly, of great help to the development of other programs)

一个小练习，是我刚学MATLAB时边看边写的(A small practice, I am just learning MATLAB writing while watching the)

A multi-band orthogonal frequency division multiplexing (OFDM) ultra wideband (UWB) system is being considered for the IEEE 802.15.3a wireless personal area networks. An enhancement to this system, named pulsed-OFDM, has been proposed to reduce the complexity and power consumption of the transceiver without sacrificing performance. In this paper, we describe a detailed implementation of a pulsed-OFDM transceiver.
