Description: 该程序描述的是数字电视地面广播中卷积交织部分.因为是卷积交织所以最后结果中出现为的数值表示该值是前一包缓冲数据的数.但针对第一包数据做卷积交织时,这些零位置上最后确实自动补零.-The procedure is described in digital TV terrestrial broadcasting in parts of Convolutional Interleaver. Convolutional Interleaver because it is so final results for the numerical value is that the previous data on the number of packet buffer. But for the first packet data do Convolutional Interleaver These zero position is indeed the last automatic zero.

Description: gps导航工具包,可用于分析GPS误差,伪距及导航融合算法-This report include the review of • Principle of Radio Navigation: navigation base on trilateration has been investigated and the over determined Eq. for navigation has been solved. • GPS Ephemeris Data: for GPS navigation, the position of GPS satellite is very important so the by receiving ephemeris data the position of the satellite is determined. • GPS Errors: Three different sources of errors in GPS navigation has been investigated (Ionosphere, Troposphere and Satellite clock). Ionospheric Error model is generated base on Parkinson [1] and the Tropospheric Error Model based on Hopfiel model [2]. • Simulation & GPS Toolbox: One of the targets of this work is generating Matlab GPS Toolbox and in one case study the performance of generated toolbox will be verified.

[GPS developskyplot

Description: SKYPLOT for a given receiver position Y=skyplot(X,PRN,C,O) draws the skyplot for the receiver position. The required inputdata for the calculation of the skyplot X is N-by-3*M matrix, where N are the timesteps and M is the number of the Satellites. The 1st colomn is the elevation, the second colomn the azimuth and the 3rd colomn is the geometric distance between sv and rx [° ° m]. The output Y is the same matrix als X, the only difference is that the satellites below the cutoffangle are marked (number 9999 is written instead the Elevation, Azimuth and distance. The numbers of the satellites are listet in the voctor PRN (M-by-1), C is the cutoffangle for the satellite elevation (default = 5°). The skyplot displays only satellites who are visible for more then 10 times.- SKYPLOT for a given receiver position Y=skyplot(X,PRN,C,O) draws the skyplot for the receiver position.
