BP神经网络预测公路运量 1.问题的描述 公路运量主要包括公路的客运量和公路货运量两个方面。据研究，某地区的公路运量主要与该地区的人数、机动车数量和公路面积有关，表1给出了20年得公路运量相关数据，表中人数和公路客运量的单位为万人，机动车数量单位为万两，公路面积的单位为万平方千米，公路货运量单位为万吨。 根据有关部门数据，该地区2010年和2011年的人数分别为73.39和75.55万人，机动车数量分别为3.9635和4.0975万辆，公路面积将分别为0.9880和1.0268万平方米。请利用BP神经网络预测该地区2010年2011年得公路客运量和公路货运量。 (BP neural network to predict the road traffic (1) description of the problem of road traffic including road passenger and road freight volume two. According to research, an area of ​ ​ road traffic and the number of the region, the number of motor vehicles and road area, Table 1 shows the 20 years have to road traffic-related data, the table number and road passenger traffic units for people , million two units of the number of motor vehicles, road area in square kilometers, the highway freight volume was 10 000 tons. According to relevant data, the number of people of the region in 2010 and 2011 were 73.39 and 75.55 million, the number of motor vehicles were 3.9635 and 4.0975 million units, the road area were 0.9880 and 1.0268 million square meters. Please use the BP neural network in the region in 2011, 2010 have highway passenger volume and road cargo.)

说明：  awgn 信道下 ldpc与FQPSK的串行级联系统，(AWGN channel，serially concatenated FQPSK modulation system with ldpc)

该程序实现改进的自适应相关算法，两个matlab文件，一个为函数，该函数求出信号特征量的马氏距离平方并通过梯度下降法训练出其固定阈值，另一个为主函数，调用该函数文件；该程序将4路信号，每一路信号特征量的马氏距离平方及其固定阈值求出来，并一起画出图来。 (The program features improved adaptive correlation algorithm, two matlab files, one for the function that calculate the square of the Mahalanobis distance of signal characteristics by gradient descent to train the fixed threshold, the other main function, call The function files the program seek out the square of the Mahalanobis distance and fixed threshold of each channel signal, there are four chanel signal,then draw them out together)
