DXT501:An SDR-Based Baseband MP-SoC for Multi-Protocol Industrial Wireless Communication

Abstract

This paper design and implement an SDR-based baseband MP-SoC DXT501. It contains four high-performance 32-bit ASIPs, a real-time 32-bit RISC processor, a high-performance dual-core 32-bit GP processor ARC HS47Dx2, and some hardware accelerators that support LTE, 4G, MulteFire, and 5G(Release15). What's more, a mobile device solution supporting multiple protocols is proposed. The practical test shows that the mobile device running on the MulteFire 1.1 protocol in the unlicensed frequency band has a transmission capacity of more than 300Mbps in uplink and 150Mbps in downlink, which can meet the requirements of modern industrial wireless communication applications such as mobile inspection robots.
