MIMO-OFDM WDM PON with DM-VCSEL for femtocells application
We report on experimental demonstration of 2x2 MIMO-OFDM 5.6-GHz radio over fiber signaling over 20 km WDM-PON with directly modulated (DM) VCSELs for femtocells application. MIMO-OFDM algorithms effectively compensate for impairments in the wireless link. Error-free signal demodulation of 64 subcar...

| Summary: | We report on experimental demonstration of 2x2 MIMO-OFDM
5.6-GHz radio over fiber signaling over 20 km WDM-PON with directly
modulated (DM) VCSELs for femtocells application. MIMO-OFDM
algorithms effectively compensate for impairments in the wireless link.
Error-free signal demodulation of 64 subcarrier 4-QAM signals modulated
at 198.5 Mb/s net data rate is achieved after fiber and 2 m indoor wireless
transmission. We report BER of 7x10−3 at the receiver for 16-QAM signals
modulated at 397 Mb/s after 1 m of wireless transmission. Performance
dependence on different wireless transmission path lengths, antenna
separation, and number of subcarriers have been investigated. |
