M=4的PSK通信系统进行蒙特卡罗仿真
仿真BPSK和4PSK调制信号在高斯信道下的性能,并与理论分析结果相比。
(1) 画出两条性能曲线,一条是根据理论平均错误概率画出,另一条是仿真曲线;
(2) 程序的基本流程:信源产生信息比特、调制、将调制信号送入信道(产生高斯白噪声的程序)、接收端检测、将检测结果与信源原始信息比较计算误符号率和误比特率;
(3) 在给定信噪比下,第二步需多次重复,以得到一个平均错误概率;
(4) 信噪比范围:BPSK(0dB – 10dB),4PSK(0dB-14dB),间隔是1dB 也可在BER=10-6左右终止。
(5) 信噪比计算 SNR=10log(Es/N0)=10log(REb/N0).

ROOTMUSIC
针对非圆信号DOA估计问题,提出了一种基于实值特征值分解 (Eigenvalue decomposition,EVD)的求根MUSIC算法.首先利用非圆信号为实值信号的特点,将阵列上的接收数据及其共轭用欧拉公式转换为实值正弦与 余弦数据,然后将正弦与余弦数据进行串联,从而扩展了数据维数.由于采用实值矩阵的EVD,因此在EVD阶段的运算量简化为复值EVD的1/4.根据 EVD后获得的信号与噪声子空间的特点,对噪声子空间和导向矩阵进行重构以便于可以使用求根MUSIC算法获取对DOA的估计.仿真实验验证了本文算法的 有效性(For the estimation of noncircular signals of DOA, proposes a decomposition value based on real valued features (Eigenvalue decomposition, EVD) the root MUSIC algorithm. Firstly, characteristics of non circular signals for real valued signals, the array data and its conjugate with the Euler formula into real value of sine and cosine and sine and cosine data. The data series, thus expanding the dimension of the data. Because of the use of real valued matrix computation in EVD, so the EVD stage was simplified as a complex valued EVD 1/4. according to the characteristics of signal and noise subspace is obtained after EVD, the noise subspace and orientation matrix reconstruction in order to facilitate the use of DOA can obtain the estimated root MUSIC the algorithm. The simulation results verify the effectiveness of the proposed algorithm)
