这是世界名曲“卡农”的matlab版本，采用m编程语言，歌曲优美动听。在学习之余不防静静聆听洗涤内心的浮躁。(This is the world famous " Canon" matlab version, the m programming language, beautiful sounds of the song. In the study anti quietly listening to the washing inner impetuous.)

说明：  假定均匀线列阵的阵元数为16。入射平面波为是频率为62.5Hz的正弦信号。阵元间距为波长的1/2。系统采样频率为1kHz，观测时间为0.4s，阵列加权方式为均匀加权，分别给出： (a)当平面波信号分别从0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100度方向入射时，主瓣指向90度方向的波束形成器的输出序列。(It is assumed that the number of elements of uniform linear array is 16.The incident plane wave is a sinusoidal signal with a frequency of 62.5Hz. The element spacing is 1/2 of the wavelength. The sampling frequency of the system is 1 kHz.The sampling frequency of the system is 1 kHz, the observation time is 0.4 s, and the array weighting mode is uniform weighting.)

A multi-band orthogonal frequency division multiplexing (OFDM) ultra wideband (UWB) system is being considered for the IEEE 802.15.3a wireless personal area networks. An enhancement to this system, named pulsed-OFDM, has been proposed to reduce the complexity and power consumption of the transceiver without sacrificing performance. In this paper, we describe a detailed implementation of a pulsed-OFDM transceiver.
