NOMA is one of the promising radio access techniques for next mobile communication generation. In this thesis, we focus on receiver design of NOMA, and we use Vienna LTE simulator as simulation environment. In chapter 4, by proportional fair scheduling, we verify that NOMA has larger total throughput than OMA, both in SISO and multi-user beamforming system. In NOMA system, near user needs to cancel stronger far user’s signal first, and then detects its signal. We compare codeword successive interference cancellation (SIC) and symbol SIC, and implement jointly modulation and detection [30]. We show that codeword SIC can approach the performance of ideal SIC. In chapter 6, we combine NOMA with SUMIMO; compare performance and complexity of various detectors. For multi-stream signal, even weak interference would seriously affect non-linear detector, so we consider weaker near user’s signal to detect far user’s signal. We propose limited search space method to reduce complexity of sphere decoder. By simulation, we show that it can reduce 15-70% complexity and maintain the same performance. We also propose adaptive detector, which can switch detector according to MCS, power factor, and SNR, so as to achieve good enough error rate and low complexity. In chapter 7, we combine NOMA with MUMIMO with multi-stream, and we need to deal with IBI at receiver side. Also, we implement limited search space method and adaptive detector to reduce complexity.

碩士 === 國立臺灣大學 === 電子工程學研究所 === 104 === Non-orthogonal multiple access (NOMA) which superposes multiple users’ signals in the power domain based on OFDM waveform, can improve system throughput. NOMA is one of the promising radio access techniques for next mobile communication generation. In this thesis, we focus on receiver design of NOMA, and we use Vienna LTE simulator as simulation environment.
In chapter 4, by proportional fair scheduling, we verify that NOMA has larger total throughput than OMA, both in SISO and multi-user beamforming system. In NOMA system, near user needs to cancel stronger far user’s signal first, and then detects its signal. We compare codeword successive interference cancellation (SIC) and symbol SIC, and implement jointly modulation and detection [30]. We show that codeword SIC can approach the performance of ideal SIC.
In chapter 6, we combine NOMA with SUMIMO; compare performance and complexity of various detectors. For multi-stream signal, even weak interference would seriously affect non-linear detector, so we consider weaker near user’s signal to detect far user’s signal. We propose limited search space method to reduce complexity of sphere decoder. By simulation, we show that it can reduce 15-70% complexity and maintain the same performance. We also propose adaptive detector, which can switch detector according to MCS, power factor, and SNR, so as to achieve good enough error rate and low complexity.
In chapter 7, we combine NOMA with MUMIMO with multi-stream, and we need to deal with IBI at receiver side. Also, we implement limited search space method and adaptive detector to reduce complexity.
