Estimation of Channel Performance of Satellite Communication and Frequency Reader

Abstract

National Remote Sensing Center (NRSC) receives data from different remote satellites like IRS-P6, IRS-P5, Cartosat-2, Cartosat-2a, etc., and processes it depending on the user requirements. The satellite data received in X band is in a particular data format. This data has to be frame synchronized using a special hardware. The receiver hardware setup must be ready at any time to make it ready it‟s performance is to be tested continuously.The frequency with which satellite data is coming is also continuously tested . In the proposed project VHDL code has been developed for BER reader with differential encoding and decoding and frequency reader. The external frequency and number of errors in satellite data will be displayed on HP display devices. This project has been implemented and tested using the ALTERA EPLDs. This needs crystal oscillators, thumb wheel switches,7 segment display etc., must be programmed as per the requirement. The hardware required for this has been implemented on the wire-warp board.
