Carrier synchronization in distributed MIMO satellite links
Deep space communications could be advantageously accomplished by using distributed multiple-input, multiple-output (DMIMO) satellite links, as it has been outlined in the recent literature. One of the most critical issues is related to synchronizing both the carrier phase and frequency, affected by Doppler shift and frequency offset at local oscillators. In this work a solution for intermittent carrier and phase synchronization is proposed, considering a baseband scheme which is suitable for both software defined radio (SDR) platforms and hybrid analog-digital higher data rate systems.
