spartanII 是xilinx公司提供的一款高性能FGPA芯片,本文详细介绍spartanII的体系结构和编程!...

把指定的噪声叠加到信号上去.有标准噪声库NOISEX-92，其中带有白噪声、办公室噪声、工厂噪声、汽车噪声、坦克噪声等等，在信号处理中往往需要把库中的噪声叠加到信号中去，而噪声的采样频率与纯信号的采样频率往往不一致，需要采样频率的校准。 (The specified noise superimposed to the signal up. Standard noise library NOISEX-92, with white noise, office noise, factory noise, car noise, tank noise in the signal processing often requires noise to be superimposed in the library The signal to noise of the sampling frequency and pure signal sampling frequency is often inconsistent sampling frequency of calibration.)

绝热电路都是使用"可逆逻辑"的低功耗电路以节省能源。与传统的CMOS电路，在开关过程中消耗能量，不同绝热电路试图节约费用由以下两个关键的规则： 永远不会打开一个晶体管时电压源之间

Frame Control field
Retry:
Set in case of retransmission frame
More fragments:
Set when frame is followed by other fragment
Power Management
bit set when station go Power Save mode (PS)
More Data:
When set means that AP have more buffered data for a station in Power Save mode

rsc递归卷积编码器是turbo码的分量编码器，递归相对于普通的卷积码多了一个反馈，拥有更好地重量谱分布和更加的误码率特性，且码率越高，信噪比越低其优势越明显。利用D触发器组成的rsc生成器，逻辑思维简单，里面包含有测试波形以及测试的结果
