  Abstract

In this paper, we design a Cell-free MIMO Testbed in which no cell boundaries exist from the user’s point of view. Synchronization, Channel Estimation, and Zero-Forcing Precoding are applied for downlink, and Channel Coding, Uplink, Channel Calibration, and UDP protocol for video transmission are implemented to verify the transmission and reception of data packets generated from real-world applications. The corresponding data processing are designed in Field Programmable Gate Array (FPGA) for fast processing. We used USRP and NI LabVIEW NXG 5.0v as hardware and software platforms, respectively. As a result of this testbed, the Signal-to-Noise Rate (SNR), Bit Error Rate (BER), and Constellation of the user equipment can be determined, as well as Channel Gain and Synchronous Correlation.
