On real-time underwater acoustic communication with a prototype modem implementation
conference paper
This study highlights a specific use case of underwater acoustic communication where the (soft) real-time requirement has relatively low impact on the system and communication performance requirements. The use case concerns acoustic monitoring, where a spectrogram of a two-minute time window is transmitted as an image. As real-time here means continuous time coverage (with some delay), this makes that the system has two minutes for computing the spectrogram, encoding the communication waveform and its transmission. It is shown that, after optimization, this requirement could eventually be met on a small general-purpose processor board using a high-level interpreted language, which is ideal for rapid prototyping. The showcase concerned a demonstration in and around the Black Sea harbour of Mangalia, Romania, in the framework of the European project in which the work was performed. Finally, some thoughts are given on further performance improvements and shortening the development cycle for research purposes.
