QAMXIANGP
本程序仿真了16QAM信号的载波相偏估计的HOS算法,整个算法实现分为(1)模拟发送端发送16QAM信号;(2)加入相偏来模拟通过信道后有相偏的测试信号;(3)利用HOS算法进行相偏估计与纠正;(4)输出星座图。(This procedure simulated a 16QAM signal carrier phase offset estimate of the HOS algorithm, the algorithm is divided into (1) analog transmitter to send 16QAM signal (2) by the inclusion of partial to simulate the channel after the phase offset of the test signal (3 ) algorithm using HOS phase offset estimate and correction (4) output constellation.)

CUMCM_prize
整数规划的一个求解方法(得到CUMCM一等奖)主要思想:找最大元之后的逐步互换求解,有点类似遗传算法(an Integer Programming Solution (with Into First Class) main ideas : after finding the greatest element gradually swap solution, it is somewhat similar genetic algorithms)

(1) 在某些无线信道中,多普勒频移会引起无线信道输出信号的混叠。请描述产生混叠的各种原因;
(2) 无线信道中的多普勒谱有一种经典谱(classic spectrum),请解释产生这种谱形状的机理;
(3) 请用Simulink工具编写代码(S-Function方式),产生一单径瑞利信道,其多普勒谱为经典谱,其中移动速率为120km/h。并请回答:证明自己用计算机产生的经典谱是正确的可能方法。
((1) in certain wireless channel, the Doppler frequency shift will be caused by wireless channel output signal aliasing. Please describe the resulting aliasing of a variety of reasons (2) wireless channel Doppler spectrum there is a classical spectrum (classic spectrum), please explain such a spectral shape of the mechanism (3) Please use Simulink tools for writing code ( S-Function mode), resulting in a single Path Rayleigh channel, the Doppler spectrum for the classical spectrum, including mobile rate of 120km/h. And please answer: prove that they used computer-generated classical spectrum is correct possible ways.)

多个脉冲积累后可以有效地提高信噪比 radar-Coherent-accumulation
多个脉冲积累后可以有效地提高信噪比,中频积累时要求信号间有严格的相位关系,即信号时相参的,所以称为相参积累。(Multiple pulse accumulation can effectively improve SNR, if integration requires strict phase relationship between signals, whereby the signal coherent, so called coherent accumulation.)
