Abstract
This letter establishes a quantized uniform circular array-based orbital angular momentum (UCA-OAM) transmission model with finite-bit analog-to-digital converters (ADCs). Based on the model, a bit error rate (BER) formula for quantized UCA-OAM systems is derived. The impact of the ADC resolution on the reliability of UCA-OAM systems is analyzed and evaluated. Results show that the quantization errors from ADCs have minimal effect on BER when the ADC resolution is above 5 bits. Additionally, with convolutional coding, UCA-OAM systems using 3-bit or 4-bit ADC can achieve BER performance comparable to systems with ideal ADC resolution.
期刊介绍：
IEEE Wireless Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of wireless communications. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments and prototypes, and new applications) are encouraged. This journal focuses on the physical layer and the link layer of wireless communication systems.
