A Theoretical Performance Analysis of Multi-User Systems with One-bit ADCs

Abstract

This paper investigates the theoretical performance of multi-user systems using One-bit analog-to-digital converters (ADCs). Through simulations with varying user configurations (10, 40 and 200 users), we observe that the uplink sum rate increases significantly for smaller user groups but tends to stabilize as the number of users grows due to multi-user interference.
As the number of base station antennas increases, the system’s capacity to handle more users improves, but the sum rate improvement slows down at higher user densities. These results provide valuable insights for optimizing system design in Multi-User systems with One-bit ADCs, highlighting that finding the right balance between the number of users and antenna numbers is essential for achieving optimal performance.
