AI Technical Summary
Current multi-antenna systems face challenges in achieving high data throughput and efficient energy consumption due to the high complexity and power consumption of digital to analog converters (DACs) in RFSoCs, which are limited by thermal resistance and quantization noise, especially in 5G and future 6G networks.
Implementing a method where individual DC offsets are added to digital signals before conversion by DACs and subsequently removed after conversion, utilizing low-resolution DACs with dynamic adaptation to reduce power consumption and improve signal quality through over-the-air combining, thereby achieving improved SNR and EVM.
This approach enhances the signal quality and reduces power consumption in multi-antenna systems by utilizing low-resolution DACs with dynamic adaptation, maintaining high performance even in varying load conditions.
