说明: 当今世界电子对抗日益激烈,对于雷达低截获和抗干扰能力的研究越来越受到关注。OFDM (Orthorgonal Frequency Division Multiplexing,正交频分复用)雷达具有大时宽带宽积、波形设计方法灵活、频谱利用率较高以及低截获性能好的特性,因此逐渐成为雷达领域的重点研究方向。除此之外,OFDM信号时域和频域波形都比较复杂,当雷达信号采用OFDM技术时,敌方很难精确估计发射信号波形和瞬时频率,使得截获机不容易分析出检测到的雷达信号。当面对敌方的欺骗式干扰时,对于同样具有大时宽带宽积的线性调频信号,OFDM信号具有更好的抗欺骗式干扰的性能,因此OFDM技术在雷达上的运用愈来愈得到关注。(As electronic warfare becomes increasingly fierce, low intercept probability radar has become an important research filed in electronic countermeasures. OFDM (Orthorgonal Frequency Division Multiplexing) radars have gradually emerged due to their high spectrum efficiency, large time-bandwidth product, flexible waveform design methods, and low intercept probability.In addition, because of the complex time-frequency characteristics of the transmitted signal in OFDM radar, the enemy is difficult to estimate the transmitted signal waveform and instantaneous frequency.When faced with enemy deception interference, OFDM signals have better anti-spoofing performance for LFM signals that also have a large time-bandwidth bandwidth product. Therefore, the use of OFDM technology in radar is attracting more and more attention. .)

说明: 基于quartus的布斯乘法器的verilog 实现。布斯乘法算法是计算机中一种利用数的2的补码形式来计算乘法的算法。该算法由安德鲁·唐纳德·布斯于1950 年发明,当时他在伦敦大学伯克贝克学院做晶体学研究。布斯曾使用过台式计算器,由于用这种计算器来做移位计算比加法快,他发明了该算法来加快计算速度。(The verilog codes of booth multiplier based on quartus. Booth multiplication algorithm is a computer algorithm using the complement form of number 2 to calculate the multiplication. The algorithm was invented in 1950 by Andrew Donald booth, who was working on crystallography at birkbeck college, university of London. Booth used a desktop calculator, and because it was faster to do shifts than to add, he invented the algorithm to speed up the calculations.)
