Abstract
In this paper we analyze the satellite DMB system E using CDM/QPSK transmission system in 2,630～2,655 MHz(25 MHz) bandwidth by computer simulation. Based on this result, we propose the protection ratio analysis and values to guarantee the Performance of the satellite DMB system E from the interference of CATV using the same spectrum. As a result, we confirmed that the protection ratio between DMB and wireless CATV should be guaranteed -16.3 dB in AWGN channel and -11.3 dB in Rician Fading(Channel model A) channel. These research results can be important fundamental material for the commercialization of satellite DMB system.
