Abstract: Abstract Precoding technique is proposed and experimental demonstrated to resist sampling frequency offset (SFO) in W-band OFDM RoF systems. Walsh–Hadamard transform (WHT)-precoding, discrete Hartley transform (DHT)-precoding, Zadoff–Chu transform (ZCT)-precoding, and orthogonal circulant matrix transform (OCT)-precoding… read more here.

Abstract: We experimentally demonstrate a real-time optical heterodyning and envelope detection-enabled orthogonal frequency-division-multiplexing-based Q-band radio-over-fiber (OFDM-RoF) system. Envelope-detector-based down-conversion is applied to the mobile terminal (MT), which makes MT insensitive to the phase noise of the… read more here.
