Abstract

This work presents over-the-air (OTA)performance, near-field bit-error-ratio (BER), and error vector magnitude (EVM) measurement using software-defined radio (SDR) in the mode-stirred metal enclosure at 5.8 GHz. The metal enclosure is stirred at 5.8 GHz using metallic paddle rotating with uniform speed. Paddle rotation creates a uniform electromagnetic field in the metal enclosure.The electromagnetic field environment in the metal enclosure can be controlled by loading the cavity with absorbing material. Field absorption can be different depending on the amount of absorbing material and location of the absorbers in the metal enclosure. It is shown that signal attenuation increases as we increase the number of absorbers. BER and EVM are measured in this environment and the performance of SDR based digital receiver is analyzed in this environment at RF frequency of 5.8 GHz.
