该脉冲位置调制与解调是通过脉冲的位置来反映调制信号的信息的-The pulse position modulation and demodulation through the pulse position modulated signal to reflect the information

用 CCS Pic C 使用 rs485 协议草案 pic 到 pic 通信。欢迎大家下载、试用。谢谢大家的支持！

现有数字信号自动调制识别方法大多只适用于无记忆信号，如PSK、ASK、FSK信号等。将有记忆 信号(MSK信号)和无记忆信号一起考虑，提出了一种改进的数字信号自动识别方法。该方法采用信号的瞬时统 计量作为特征参数，采用多层神经网络作为分类器。计算机仿真表明：当噪声采用高斯白噪声，并且信噪比大于 l5 dB时，识别率高于96％ ；当信噪比不低于l0 dB时，识别率不低于90％。-Existing digital signal automatic modulation recognition methods are mostly applied only to memoryless signals, such as PSK, ASK, FSK signals. Will have a memory signal (MSK signal) and non-memory signal into consideration, an improved digital signal automatic identification method. This method is the use of the instantaneous signal statistics as a characteristic parameter, the use of multi-layer neural network as classifier. Computer simulation shows that: When the noise using Gaussian white noise, and signal to noise ratio greater than l5 dB, the recognition rate is higher than 96 when the signal to noise ratio not less than l0 dB, the recognition rate of not less than 90.

多天线的角辐射功率演示,包括2种天线阵,1为线性真,一为任意布置.-A MATLAB GUI platform for displaying the radiation pattern of a narrowband beamformer with user-defined array geometry. User can specify the array geometry, directions of incoming signals, noise level, and the types of beamformer by mouse clicks. Useful for gaining insight about collaborative beamforming in sensor networks and random arrays.
