Comparison of various Hardware Architectures for the Shared UE-Side Distributed Antenna Component

摘要

Shared UE-side Distributed Antenna System (SUDAS) is a very promising technique in order to deliver an improved coverage and high throughput beyond 10 Gbit/s to the users in the indoor and intra-vehicular scenarios for 5G applications. This paper presents an implementation perspective and comparison analysis of different candidate hardware architectures suitable for the Shared UE-side Distributed Antenna Component (SUDAC), which is the main building block of the SUDAS and acts as a relay and performs massive spatial-to-frequency domain translation and vice versa. Based on the defined comparison criteria and scoring of different architectures, it has been established that Analog SUDAC with Slight Frequency Shifting (SFS), Analog SUDAC with Digital Control, Digital SUDAC with 802.11ad and Digital SUDAC with Frequency Domain Equalization (FDE) are the top candidates for hardware implementation and future deployment.
