摘要：
未来无线通信系统预计将在100GHz以上频段运行。模数转换器因高分辨率带来的高能耗，是未来无线通信系统的瓶颈——这类系统要求接收端设备具备低能耗、低复杂度特性。本文针对采用1比特量化与过采样的多用户多输入多输出下行链路系统，推导了一种基于服务质量约束的新型预编码方法。该场景下采用将信息承载于过零点的时域过零调制（time-instance zero-crossing modulation）。与已有研究不同，本文的约束与距判决门限最小距离对应的符号错误概率相关。数值结果展示了所提预编码方法在不同参数下的性能表现。
英文摘要：
Future wireless communications systems are expected to operate at bands above 100GHz. The high energy consumption of analog-to-digital converters, due to their high resolution represents a bottleneck for future wireless communications systems which require low-energy consumption and low-complexity devices at the receiver. In this work, we derive a novel precoding method based on quality of service constraints for a multiuser multiple-input multiple-output downlink system with 1-bit quantization and oversampling. For this scenario, the time-instance zero-crossing modulation which conveys the information into the zero-crossings is considered. Unlike prior studies, the constraint is given regarding the symbol error probability related to the minimum distance to the decision threshold. Numerical results illustrate the performance of the proposed precoding method evaluated under different parameters
