RDP_algorithm
曲线数据压缩是计算机图形学、计算机自动制图和地理信息系统( GIS) 等学科理论与方法研究的一个重要问题,其实质是一个信息压缩问题.RDP 算法是应用最为广泛的一种,由于容易编程实现且压缩结果较好, GIS 界许多著名商业软件公司(如Intergrap h ,ESRI ,LaserScan) 都把此算法作为其制图系统中一种曲线数据压缩的标准算法.(the well-known Ramer-Douglas-Peucker (RDP) algorithm for polyline data compression)

Doppler-spectrum-of-radio-channel
1. 关于无线信道的多普勒谱,请回答以下问题:
(1) 在某些无线信道中,多普勒频移会引起无线信道输出信号的混叠。请清楚的描述产生混叠的各种原因;
(2) 无线信道中的多普勒谱有一种经典谱(classic spectrum),请解释产生这种谱形状的机理;
(3) 请用S-function产生一单径瑞利信道,其多普勒谱为经典谱,其中移动速率为120km/h。并请回答:证明自己用计算机产生的经典谱是正确的可能方法。
(Doppler spectrum of radio channel 1, please answer the following questions
(1) In some wireless channel, radio channel Doppler shift will cause the output signal aliasing. Please clearly describe aliasing for various reasons )
