  Abstract

This paper describes the implementation of analog beamformer which operates on 13.8 GHz carrier frequency using USRP(universal software radio peripheral). MIMO(multiple-input multiple-output) channel transceiver system is composed of two beamformer testbeds, which use identical ULA(uniform linear array) antennas. Transmit end sends signal modulated by OFDM(orthogonal frequency division multiplexing)/QPSK(quadrature phase shift keying), and receive end measures RSS(received signal strength) and EVM(error vector magnitude) during demodulation. This research compares and analyzes the RSS and EVM depending on whether beams are aligned or misaligned.
