High-speed data transmission system based on QPSK scheme in substrate integrated waveguide

Substrate integrated waveguide (SIW) is regarded as an available interconnects solution for high-speed data transmission. In this paper, in order to further improve the data rate and bandwidth usage, an SIW interconnect system based on Quadrature Phase Shift Keying (QPSK) modulation and demodulation technique is proposed. The associated theoretical models validate the feasibility of the presented system. A fabricated SIW prototype with 14-28 GHz bandwidth is experimentally evaluated in the developed SIW QPSK data communication system. Experimental results demonstrate that an excellent eye opening and low error rates are obtained with different Pseudo Random Binary Sequence (PRBS) bit sequences at the rate of 10 Gb/s. Compared with traditional mixing modulation scheme, our proposed system can improve transmission rate from 5 Gb/s to 10 Gb/s and achieve error-free operation (BER<;10-12) with 27-1 pattern.
