混合动力汽车(HEV)是在电动汽车发展过程中出现的一种低油耗、低排放、续驶历程长、价格适中,兼具纯电动汽车和传统燃油汽车优点的新型汽车,由于在技术、经济和环境等方面的综合优势,HEV 被认为是目前最切实可行的清洁汽车方案。本文以混合动力轿车项目及其整车控制系统子课题为背景,主要研究HEV 的控制策略及其在实车上的应用。包括用matlab对汽车及其控制系统建模优化。(Hybrid electric vehicle (HEV) is in the process of development of electric vehicles the emergence of a low fuel consumption, low emission, long-driving course, affordable, both pure electric vehicles and conventional fuel vehicles the benefits of new cars, due to technical, economic and environmental aspects of the comprehensive advantages, HEV is considered to be the most viable clean vehicle program. In this paper, hybrid cars and the vehicle control system sub-project issues as background, the main research HEV control strategy and its application in the real car. Including the use of matlab modeling of the vehicle and its control system optimization.)

BER瑞利信道采用QPSK
本文讨论了QPSK在Rayleigh信道中的误码率性能,包括理论Rayleigh模型和AWGN(Additive White Gaussian Noise)下的误码率,并与仿真结果进行了比较。模拟信号通过瑞利信道进行调制并添加AWGN。然后对Rayleigh信道进行分频解调,并对误差进行统计,得到QPSK的误码率性能

波束形成
从时域波形入手,用matlab仿真了一定信噪比下,等阵元间距水平直线阵的阵元间距与波长比值d/lamda,阵元数N以及信号入射角sita对时域波束形成分辨率的影响。
具体matlab程序见压缩包。
仿真结果表明:
(1)阵元间距与波长比值不能超过1/2,如果超过1/2,则扫描扇面内会出现栅瓣导致方位估计模糊。
(2)在信号入射方向、阵元数一定的情况下,阵元间距与波长之比在满足不超过1/2的前提下越大,主波束越窄。特殊的,当信号沿直线阵法向入射时,主波束宽度同阵元间距与波长的比值近似呈反比例关系。
(3)在信号入射方向、阵元间距与波长比值一定的情况下,阵元数越多,主波束越窄。特殊的,当信号沿直线阵法向入射时,主波束宽度与阵元数近似呈反比例关系。
(4)在阵元数,阵元间距与波长比值一定的条件下,当声信号沿阵的法向入射时主波束最窄,阵的指向性最好,当入射信号沿端向(与直线阵平行方向)入射时主波束最宽,阵的指向性最差。
