“…An OFDM-UWB fully-compliant WiMedia channel centered on 4.488 GHz with 528 MHz bandwidth and using dual carrier modulation (DCM) at 480 Mbit/s [6] was transmitted through different fiber links. DCM MB-OFDM UWB systems have a high PAPR problem [3] which is reduced using the DD-MZ proposed scheme. Figure 6(c) shows the EVM performance of both modulators using the OFDM-UWB signal.…”

“…Transmitter digital-to-analog converters for radio systems employing orthogonal division multiplexing (OFDM) modulation such as ultra-wide band (UWB) require a linearity of at least 25 dB [2]. Multi carrier signals with large number of sub-channels like multi-band OFDM-UWB signals have large peak-to-average power ratio (PAPR) which joint with the high bandwidth of each UWB channel (528 MHz) is the main limitation of intensity-modulation systems [3]. In this work, a dual drive (DD) Mach-Zehnder (MZ) architecture with enhanced linearity and chirp controlled modulation scheme was designed, characterized and applied to radio-over-fiber transmission of high PAPR signals.…”

A dual-drive LiNbO 3 architecture modulator with chirp management is proposed and developed offering SFDR > 25 dB in a 1.4 V bias excursion compared to only 0.5 V bias excursion in a conventional Mach-Zehnder electro-optical modulator (MZ-EOM). The architecture effectively extends the linear regime and enables the optical transmission of wireless systems employing orthogonal division multiplexing (OFDM) modulation such as ultra-wide band (UWB) which require high linearity over a broad frequency range due to their high peak-to-average power ratio (PARP). Radio-over-fiber UWB transmission in a passive optical network is experimentally demonstrated employing this technique, exhibiting an enhancement of 2.2 dB in EVM after 57 km SSMF when the dual-drive developed modulator is employed.

Contiguous channel bonding for using more than one channels together in TV white space has been considered in the IEEE 802.22-specified wireless regional area network system. To support more flexible channel usage, this paper investigates noncontiguous channel bonding as a potential extended feature of IEEE 802.22 standard. The transceiver structure with Non-Contiguous OFDM (NC-OFDM) transmission to support non-contiguous channel bonding is presented. The simulation results show that non-contiguous channel bonding achieves better symbol error rate performance with slightly higher peak to average power ratio comparing with contiguous channel bonding. Finally, the power spectrum density of NC-OFDM signals with non-contiguous channel bonding is analyzed and the number of additional guard subcarriers for mitigating out-of-band emissions are determined to comply with the required transmission spectrum mask.
