摘要

本文研究了无线传感器和执行器网络(WSAN)接收机中模数转换器(ADC)的量化和裁剪联合效应。作为一种超可靠低延迟通信(URLLC)系统,采用码分多址(CDMA)和正交频分复用(OFDM)相结合的偏置正交调幅(OQAM)技术。研究表明,在工业非视距(NLOS)信道下,当两种传输都受到随机跳频干扰(RFHJ)攻击时,CDMA-OQAM-OFDM的性能优于CDMA-OFDM。

Analysis of ADC Quantization and Clipping Effects on CDMA-OQAM-OFDM-Based WSAN
In this paper, the joint effect of quantization and clipping done by the Analog-to-Digital Converter (ADC) in the receiver of a Wireless Sensor and Actuator Network (WSAN) is investigated. As an Ultra Reliable Low-Latency Communication (URLLC) system, a combination of Code Division Multiple Access (CDMA) and Orthogonal Frequency Division Multiplexing (OFDM) that uses Offset Quadrature Amplitude Modulation (OQAM) is applied. It is shown that under an industrial Non-Line-Of-Sight (NLOS) channel, CDMA-OQAM-OFDM outperforms CDMA-OFDM when both transmissions are attacked by Random Frequency Hopping Jamming (RFHJ).
