TÓM TẮT
In this paper, we study the performance of a
millimeter-wave subcarrier multiplexed radio-over-fiber
(MMW/SCM/RoF) system using coherence detection and
compare its performance with a direct detection based scheme. A
system model for performance analysis is presented, showing the
relationship of SNR, BER or receiver sensitivities with power of
local oscillator, bit rate, number of subcarrier channels for ASK,
QPSK, and BPSK modulation formats. We propose to use
sensitivity gain as an important parameter to describe the
performance improvement of the coherent detection with respect
to the direct detection scheme. Our performance analysis
indicates that the coherent detection significantly improves the
system performance with a sensitivity gain by approximately 11
dB and 7 dB for system using 100 Gb/s and 500 Gb/s signals,
respectively.
