时间同步后即可确定每帧数据的起始位置,这样就能完整的截取下每一帧。但是,数据中还带有频偏信息。在常规的通信系统中,多普勒很小仅仅会带来很小的频偏,但是在大多普勒的情况下,频偏将非常大,20马赫的速度将会带来将近34K的频偏。因此,如何很好的纠正频偏即为本系统的难点。
OFDM中,我们将大于子载波间隔倍数的频偏称为整数倍频偏,而将小于一个子载波间隔的频偏称为小数倍频偏。频偏矫正精度只要能保证小于十分之一倍的子载波间隔,频偏就不会对均衡和解调造成影响。本文中我们借鉴这种思想,由于硬件资源限制,我们将在接收端做64点FFT,即相当于将频域划分为64份,我们将小于 的频偏称为小数倍频偏,将 整数倍的频偏称为整数倍频偏。本程序即基于SCHIMDL经典方法完成小数倍频偏纠正(After time synchronization can determine the starting position of each frame data, so you can complete the interception of each frame. However, in the data with frequency information. In conventional communication systems, doppler small will bring only small deviation, but in the case of most of the doppler, frequency PianJiang is very large, 20 Mach speed will lead to deviation of nearly 34 k. Therefore, how to good to correct deviation is the difficulty of this system.
OFDM, we will be bigger than the sub-carrier spacing ratio of frequency deviation is called the integer frequency offset, and the interval will be less than a child carrier frequency offset is called decimal frequency doubling. Deviation is less than one over ten times as long as can guarantee accuracy of sub-carrier spacing, deviation will not affect balance and demodulation. This article, we draw lessons from the idea, due to the limited hardware resources, we will do 64 points FFT at the receiving end, which is equ)

修改后的展位乘法的两个华莱士算法签名和签名二进制数
这个项目修改后的展位华莱士算法给出了所需的方法来实现一种高速度和高性能并行计算的复数模拟乘法器。设计的结构使用基数 4 修改 Booth 算法和华莱士树。这两种技术来加速增殖过程,作为他们的能力,以减少局部产品代到 11/2 和压缩部分产品期限按比例为 3 ∶ 2。尽管如此,携带保存加法器 (CSA) 是用来增强系统的加法过程的速度。设计了系统有效地使用 VHDL 代码为 8 x 8 位签署数字和成功的模拟.
Booth 型乘法器可以减少迭代步长,以执行乘法比较常规步骤操作次数。Booth 算法 "扫描" 乘法器操作数,并跳转到链的这种算法可以减少产生相对于常规的乘法算法,每个位的乘数乘以与被乘数和部分产品对齐和加在一起的结果所需的加法次数。更有趣的是加法次数是数据依赖
