We are experts on HF propagation and application of wideband modulation to the HF channel, taking into account the daily, seasonal and inter-annual variations. Expertise on the complete design of an HF radio communication system: starting for the channel modeling, continuing with the design of the most adequate broadband modulation, and implementing the radio-modem with software radio technology and programmable logic devices (FPGA’s). We are also experts on applying multi-antenna diversity and MIMO technologies to the ionospheric channel, in order to improve the robustness and the capacity of the communication system. We have a full equipped radio lab, so we can install and check any radio installation, and we have a lot of experience on field work. Ricard Aquilue raquilue@salle.url.edu
