“…Single-carrier quadrature-phase-shift keying (QPSK) signals are used for long-haul lightwave systems [1,2]. Performing close to the matched-filter limit [3,4], coherently detected QPSK signals may use digital signal processing (DSP) to compensate for chromatic and polarization-mode dispersions [5][6][7].…”

“…Fifthly, the BER is calculated by comparing the received bits after demodulation with the original bits. In this experiment, for the BER calculation, 506880 bits (660 data symbols, and each symbol contains 768 bits) were measured [24]- [27].…”

We experimentally demonstrated a seamlessly integrated fiber-wireless system that delivers 30.67-Gb/s polarization division multiplexing-multiple input multiple output-orthogonal frequency division multiplexing (PDM-MIMO-OFDM) signal through 40-km fiber and 5-m wireless transmission over free-space at 100 GHz adopting heterodyne coherent detection. De-multiplexing is realized by channel estimation based on a pair of time-interleaved training sequences (TSs). The bit-error ratio (BER) for the 30.67-Gb/s PDM-MIMO-OFDM signal is less than the pre-forward-error-correction (pre-FEC) threshold of when the optical signal-to-noise ratio (OSNR) is larger than 19.3 dB after both 40-km single-mode fiber-28 (SMF-28) transmission and 5-m wireless delivery at 100 GHz. We also find that the BER performance is sensitive to the multipath effects induced by the transmission distance difference in the wireless link.

“…The analog-to-digital conversion is realized in the digital oscilloscope with the sample rate of 80 GSa/s and the electrical bandwidth of 25 GHz. The subsequent offline digital signal processing (DSP) includes clock recovery, CD compensation, constant-modulus-algorithm (CMA) equalization, carrier recovery, differential decoding and BER counting [20,21]. When the 28-Gbaud PDM-QPSK signal is carried by one of the generated optical subcarriers based on the cascaded DML (NEL NTT NLK1551SSC) and PM scheme driven by different RF clocks shown in Fig.…”
