teqc生成那8个compact文件，注意不是compact2或compact3，可以快速画图，比qcview方便多了，又快有美观！至于compact文件我会另外上传！( TEQCFV Read and plot TEQC report files (fast view) TEQC is the Toolkit for GPS/GLONASS/SBAS Data used to solve many pre-processing problems with GPS, GLONASS, and SBAS data: TEQC stands for Translation, Editing, and Quality Check More info here: http://facility.unavco.org/software/teqc/teqc.html TEQCFV(FILENAME) returns the content of a TEQC reportfile in a figure (and a matrix). Input argument FILENAME is optional. Valid TEQC report files are: FORMAT DESCRIPTION *.sn1 Signal to noise ratio (S/N) Carrier L1 *.sn2 Signal to noise ratio (S/N) Carrier L2 *.iod Derivative of ionospheric delay observable (m/s) *.ion Ionospheric delay observable (m) *.mp1 Multipath Carrier L1 *.mp2 Multipath Carrier L2 *.azi Satellite azimuthal data (degrees) *.ele Satellite elevation data (degrees))

调制信号的识别。比如2ASK,2PSK,2FSK 、QAM等调制方式的信号识别。(Identification of the modulation signal.For example 2ASK, 2PSK, 2FSK, signal recognition QAM modulation scheme.)
