16QAM High-Speed Transmission System Using Substrate Integrated Waveguide-Type Interconnect

SHEN Li-mei;LI Xiao-chun;MAO Jun-fa;Key Laboratory of Design and Electromagnetic Compatibility of High Speed Electronic Systems of Ministry of Education,Shanghai Jiaotong University;  
To improve the data transmission rate,in this paper a novel design and implementation of a highspeed interconnect system was proposed based on SIW(substrate integrate waveguide)using hexadecimal quadrature amplitude modulation(16QAM)technique.The inserted loss of the fabricated SIW is appoximately 0.5dB within a bandwidth of 14 to 28GHz;the maximum data rate of the 16 QAM interconnection system is 20Gb/s,and a clear eye diagram and constellation diagram is obtained through simulation in ADS(advanced design system).The data rate of the proposed 16 QAM high-speed interconnect system is 4times than that of the conventional system using high-frequency carrier modulate method.Therefore,the proposed 16 QAM SIW-based system significantly improves the bandwidth efficiency of SIW and the data transmission rate of the interconnect system.
