碩士 === 國立交通大學 === 電信工程研究所 === 105 === Two important application scenarios in 5G mobile communication are known as enhanced-mobile-broadband (eMBB) and ultra-reliable low-latency communication (URLLC). In this thesis, we consider the eMBB and URLLC multiplexed system. A critical problem in the system is that how to detect the URLLC data at the receiver reliably. We propose two types of schemes to conduct the detection, blindly. The first method rotates URLLC constellations at the transmitter and uses the automatic-modulation-classification scheme at the receiver. The second method uses precoding schemes adding correlation for URLLC data. A simple correlation-estimation scheme can then be used at the receiver to conduct the detection. Theoretical classification error rate and symbol error rate are also derived such that an optimization scheme can be formulated to determine optimum parameters. Simulations show that the proposed methods can yield satisfactory results and indicator may not be necessary.
