本文提出了一种用于短符号、大规模机器类型通信(mMTC)和物联网(IoT)应用的新型时频弯曲波形。波形由不对称的升余弦(RC)脉冲组成,以增加时域和频域中的信号包容性。该波形在时域中具有低功率尾部,因此在存在延迟扩展和时间偏移的情况下具有更好的性能。应用时间轴扭曲酉变换来控制时频空间中的波形占用,并补偿符号边缘处的高滚降因子脉冲的使用。本文解释了一个逐步的分析,以确定滚降因素的档案和翘曲函数。在仿真部分中,给出了传统零尾离散傅立叶变换-扩展-正交频分复用(ZT-DFT-s-OFDM)和循环前缀(CP)DFT-s-OFDM方案的增益。
This paper proposes a novel time-frequency warped waveform for short symbols, massive machine-type communication (mMTC), and internet of things (IoT) applications. The waveform is composed of asymmetric raised cosine (RC) pulses to increase the signal containment in time and frequency domains. The waveform has low power tails in the time domain, hence better performance in the presence of delay spread and time offsets. The time-axis warping unitary transform is applied to control the waveform occupancy in time-frequency space and to compensate for the usage of high roll-off factor pulses at the symbol edges. The paper explains a step-by-step analysis for determining the roll-off factors profile and the warping functions. Gains are presented over the conventional Zero-tail Discrete Fourier Transform-spread-Orthogonal Frequency Division Multiplexing (ZT-DFT-s-OFDM), and Cyclic prefix (CP) DFT-s-OFDM schemes in the simulations section.
