Analysis of ADC Quantization and Clipping Effects on CDMA-OQAM-OFDM-Based WSAN

Abstract

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).
