Physical layer design towards VHF Data Exchange (VDE) Link
Enhancing diversity techniques allow long time code bit interleavers with strong channel codes to offer enough margin to cope with a satellite system in parallel. However, for channel codes which need to cope with voice applications a much shorter delay has to be considered. Therefore, artificially enhancing diversity techniques could resolve this even voice communication links. VDES could then also serve as a joint data and voice communication service. We further investigated the PAPR of singleand multicarrier systems. The impact of the roll-off factor showed about 1.5 worse PAPR compared to a multi-carrier system with only eight subcarriers. The loss could be partially compensated by techniques that shape the signal before the power amplifier to optimize the communication link.
