H 2020-ICT-2016-2 RIA Project-ID : 761329 WORTECS Networking research beyond 5 G D 3 . 2 Common Analog and Digital Baseband Design for Flexible Radio and Optical Transceiver

This deliverable focuses especially on radio and optical transmissions. The main issue of this document is to try to find a common architecture between the radio and optical transmitter in order to mutualize as much as possible the implementation. Starting from the analysis of the propagation channel characteristics of both systems, we argue about the choice of the modulation format when also taking into account some material constraints issued from the hardware components. Then, Tx and Rx description and limitations of analog radio and optical parts are pointed out before describing the main elements composing the radio and optical baseband system physical layer. In conclusion, we propose three main possibilities for mutualizing the radio and optical transmitter platforms.
