Liz Mart\u00ednez Marrero Wins Best Student Paper Award for Work Applying Precoding to Distributed Satellites.\u00a0<\/p>

Satellite precoding, a technique being developed by SnT\u2019s SigCom<\/a> team, is positioned to revolutionise satellite communications. The technique allows multiple transmissions to be sent on the same signal, figuratively piggybacking them one on top of the other. This allows a much larger bandwidth to be used to transmit the signal and will significantly improve connection speeds. The technology is built on a technique called ‘precoding’, which allows for interference on the frequency in use to be cancelled out.\u00a0\u00a0\u00a0<\/p>

The impact of this precoding technique will be enormous. ‘It will dramatically increase the amount of information any single satellite can transmit,’ says Liz Mart\u00ednez Marrero<\/a>, a PhD candidate at SnT who is working on the project. Liz\u2019s work within this project focuses on the hardware used to broadcast satellite signals, including the new precoded signals. ‘Part of the appeal of this method is that it does not depend on hardware updates. There\u2019s no need to launch any new satellites, which would be very expensive, or even to update the hardware here on Earth. And that\u2019s what my recent paper \u2018Effects of multiple oscillator phase noise in precoding performance\u2019 helped to confirm.’ In fact, her paper was recently presented at the 37th International Communications Satellite Systems Conference<\/a>\u00a0where it won the conference\u2019s Best Student Paper Award.\u00a0<\/p>

‘It is always nice to receive this sort of acknowledgement from your peers in the field,’ continues Mart\u00ednez Marrero. ‘But within the context of a project like this, which could have such a widespread impact on the future of the whole satellite communication field, it is particularly exciting.’ Her paper found that while the transmitter\u2019s independent oscillators do degrade the signal\u2019s performance, the precoding technique is capable of effectively compensating for that degradation. ‘This is important because it means not only that it is possible to transmit from existing satellites, but also that even if we use groups of different satellites cohesively as distributed satellite networks, the precoding technique remains effective,’ says Mart\u00ednez Marrero.\u00a0\u00a0<\/p>

The efficacy of the precoding method for distributed satellite networks is essential to the viability of the technique in the future. Distributed satellites can achieve stronger signals, which would mean better connection speeds on earth, and they do this while using smaller, more economical hardware. ‘Distributed networks use smaller satellites, but more of them. And they are then used cohesively, with a much bigger result,\u201d says Liz. ‘The next step in my research is to continue investigating other potential barriers to implementing distributed satellite networks.’<\/p>
