A Satellite On-board OFDM Switch System based on Network Coding
Satellite on-board network switch technology is one of the key technologies of satellite network system.Orthogonal Frequency Division Multiplexing has high spectrum utilization and can outperform anti-multipath fading ability efficiently.Each sub-carrier wave of OFDM signal can be used independently; therefore satellite on-board OFDM switching system has received widespread attention.Satellite network coding,one of the heated research fields of satellite network system,becomes the core of satellite switching technologies gradually.This article will expound the advantages of these two technologies and design a satellite on-board OFDM switching system,which has a greater channel capacity.At last,a simulation of the system demonstrates the theory can be realized.
