Abstract

Next-generation Internet of Things (IoT) systems require faster data transmission, support for moving objects, and long-distance transmission when compared to the currently available IoT systems. The IEEE 802.15.4 smart utility network (SUN) orthogonal frequency-division multiplexing (OFDM) can satisfy these requirements. Mobile-communication-oriented receiver systems are typically used in urban environments for SUN OFDM. However, the evaluation depends on computer simulations and requires an experimental evaluation platform based on software-defined radio (SDR) that can modify transmitter-receiver functions. We present a platform for SUN OFDM that enables high-speed mobile communication. The proposed platform comprises a signal generator-based transmitter and an SDR-based receiver; the receiver baseband signal processing is performed by MATLAB. We also proposed signal processing functions that can receive the SUN OFDM packets even at speeds of tens of km/h. We applied a simplified universal time-domain windowed (UTW)-OFDM scheme to this platform to operate even at sub-1 GHz, where the spectrum mask is more limited. In the experimental evaluation, the required packet error rate for SUN OFDM was achieved in an 80 km/h multipath fading environment, and out-of-band emission can be suppressed by over 43 dB from the peak power while achieving performance equivalent to that without applying the simplified UTW.
基于软件定义无线电的 IEEE 802.15.4 SUN OFDM 评估平台,适用于高度移动环境
与目前可用的物联网系统相比,下一代物联网(IoT)系统需要更快的数据传输、支持移动物体和长距离传输。IEEE 802.15.4 智能公用事业网络(SUN)正交频分复用(OFDM)可满足这些要求。面向移动通信的接收器系统通常用于城市环境中的 SUN OFDM。然而,评估依赖于计算机模拟,需要一个基于软件定义无线电(SDR)的实验评估平台,该平台可修改发射机-接收机功能。我们提出了一个可实现高速移动通信的 SUN OFDM 平台。所提议的平台包括一个基于信号发生器的发射器和一个基于 SDR 的接收器;接收器的基带信号处理由 MATLAB 完成。我们还提出了信号处理功能,即使在几十公里/小时的速度下也能接收 SUN OFDM 数据包。我们将简化的通用时域窗口(UTW)-OFDM 方案应用于该平台,即使在频谱掩码较为有限的 1 GHz 以下频率也能运行。在实验评估中,SUN OFDM 在 80 km/h 的多径衰落环境中达到了所需的数据包错误率,带外发射的峰值功率被抑制了 43 dB 以上,性能与未应用简化 UTW 时的性能相当。
