We experimentally demonstrate a novel SNR-enhanced RoF scheme based on digital-analog modulation and phase-modulation-induced bandwidth expansion, achieving 18dB SNR gain at half the spectral efficiency and 10dB SNR gain at 3/4 spectral efficiency. EVM of 1.41% is realized for 256QAM-OFDM-DA-APM signal with 5GHz carrier.
