| Outline of Final Research Achievements |
In this project, to develop a high performance seamless fiber-wireless system for precision analog waveform transmission of mobile signals, several methods were developed, including: (1) a high-quality millimeter-wave signal generation using a high-precision optical modulation technology; (2) a stable and low phase noise self-homodyne detection; (3) a high spectral efficiency and low fiber dispersion fiber-wireless transmission; and (4) a low distortion and interference and high spectral efficient multi-band transmission. Using the developed methods, a high-precision analog waveform transmission of wideband wireless signals over the system was experimentally confirmed. The test signals included wideband (several GHz bandwidth) and high-order modulation format (64-QAM, 256-QAM) signals.
