Millimeter-wave 2×2 MIMO SC-FDE for an 8K wireless camera

Abstract

We previously developed a high-definition (HD) wireless camera using millimeter waves with the orthogonal frequency division multiplexing (OFDM) scheme. Now, we are developing an 8K wireless camera that can achieve larger transmission capacity with a smaller transmitter. Considering this, we study a single-carrier scheme with frequency domain equalization (SC-FDE) and a multiple-input multiple-output (MIMO) scheme. The SC-FDE could achieve a smaller peak-to-average power ratio, resulting in a smaller power amplifier. In this paper, we propose two structures of 2×2MIMO SC-FDE and evaluate their basic performance in several scenarios with computer simulations.
