50-Gb/s Radio-over-Fiber System Employing MIMO and OFDM Modulation at 60 GHz

Abstract

Record 50-Gb/s wireless signal transmission over 4 m is experimentally demonstrated using a 2×2 MIMO Radio-over-Fiber system at 60 GHz. MIMO spatial multiplexing and 16-QAM OFDM modulation were used to achieve a high combined spectral efficiency of up-to 8 b/s/Hz.
