摘要：

为了进一步提高数据的传输速率，采用16进制的正交振幅调制(16QAM)方式，设计实现了一种新颖的基于基片集成波导互连的高速数据传输系统.基片集成波导经设计加工和测试，其带宽为14~28 GHz，通带内插损约为0.5 dB；16QAM互连系统经先进系统设计(ADS)软件仿真验证, 得到了清晰的眼图及星座图，最大传输速率可达到20 Gb/s，是传统基片集成波导(SIW)互连系统的数据传输速率的4倍.因此，采用16QAM的SIW高速互连系统与传统的采用载波调制方式的SIW互连系统相比,可显著增加SIW的频带利用率,进而提高系统的数据传输速率.

Abstract:

To improve the data transmission rate, in this paper a novel design and implementation of a highspeed 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 0.5 dB within a bandwidth of 14 to 28 GHz; the maximum data rate of the 16QAM interconnection system is 20 Gb/s, and a clear eye diagram and constellation diagram is obtained through simulation in ADS(advanced design system). The data rate of the proposed 16QAM highspeed interconnect system is 4 times than that of the conventional system using highfrequency carrier modulate method. Therefore, the proposed 16QAM SIWbased system significantly improves the bandwidth efficiency of SIW and the data transmission rate of the interconnect system.

Key words: substrate integrate waveguide, hexadecimal quadrature amplitude modulation(16QAM), highspeed interconnect
