Over-the-air investigation of transmitter and receiver nonlinear distortion using a mm-wave MIMO testbed
Paper in proceedings, 2020
In this paper, we evaluate the nonlinear distortion of the transmitter (Tx) and receiver (Rx), separately, of the developed mm-wave testbed at Chalmers University of Technology, MATE, using Over-The-Air (OTA) measurement. The developed testbed has been designed to operate within 27 - 31 GHz frequency range, with 1 GHz analog bandwidth per Tx or Rx. An overview on the system configuration has been provided. In order to evaluate the limitations of the proposed testbed, we have conducted several experiments on nonlinear distortion effects of the constructed Tx and RF frontends.
