| 英文摘要 | Digital backends are critical for modern radio interferometers, enabling wideband signal acquisition and flexible data processing. We present the design of a new RFSoC-based backend developed for the Central China Array (CARRY), currently under construction in Hubei, China. The system, built on the RFSoC-xczu47DR platform, supports wideband sampling of eight inputs at 1 GSPS with polyphase filter bank processing, channel equalization, and high-speed 100 GbE data transmission. Experimental results confirm reliable synchronization, high linearity, and stable spectral processing. This design provides CARRY with a high-performance, scalable, and cost-efficient reference architecture that can be extended to other radio interferometer arrays. |
