Example code to program a C8051F30x device through its C2 interface.-Example code to program a device C8051F30x through its C2 interface.

一种基于FPGA 实现的全并行结构FFT 设计方法，采用全并行加流水结构, 可在一个时钟节拍内完成32 点FFT 运算的功能, 设计最高运算速度可达11ns-FPGA-based parallel architecture to achieve the full FFT design methodology, the use of the entire parallel increase in water structure, in a beat the clock to complete 32-point FFT computation function, the design maximum speed of up to 11ns

在窄带Rayleigh快衰落信道下几种检测方法的误码率性能比较-In the narrow-band Rayleigh Fast Fading Channels Several detection methods of error rate performance comparison

该项目用于降低 PAPR ofdm 系统中，通过使用不同的技术。OFDM 峰均功率比的主要缺点是降低系统性能，因为它在 ofdm 到平均功率高的高峰。并且在这里我们使用非线性压扩变换来减少此峰均比。

串口通信的书籍，主要讲述串行通信原理，从底层详细讲解。-Serial communication books, mainly on the principle of serial communication, from the bottom to explain in detail.

这是Remon Spekreijse写的一个串口类，功能十分强大！-Remon Spekreijse This is written in a serial type, function is very powerful!

端口专家是一个优秀的端口（串口、并口）监视、调试程序，有以下基本功能： 1.能动态设置各种通讯速率、奇偶校验、数据位、停止位和流控； 2.可以16进制形式自动显示接收到的数据，并能同时发送ASCII码（包括中文）和16进制字符串，可以任意设定自动发送周期,定时发送数据； 3.能将接收数据保存成文本文件,便于比较观察；并能发送任意大小的数据文件（以二进制形式发送）； 4.能自动保存设置参数，无需每次重新设置。-port experts is a good ports (serial, parallel) monitoring, debugging procedures, the following basic functions : 1. Dynamically created various communications rate, parity, data bits, stop-and flow control; 2. May 16-band automatic form of data received and at the same time sending ASCII (including Chinese) and 16 string band can be set to automatically send arbitrary cycle, regularly send data; 3. preservation can receive data into text files, facilitate comparison of observation; and the ability to send any size of paper (in binary form Send); 4. Save the settings automatically parameters, each without re-instated.
