Implementation of the Transmitting Functionality on the TIGER-3 FPGA-based Transceiver Platform
High Frequency (HF) radio waves (3-30 MHz) are commonly used in long-range communication applications or in radars that require long-range detection capabilities. This is due to the refraction of HF radio waves, where the transmitted wave bends back towards to the Earth. HF radio waves can therefore...

High Frequency (HF) radio waves (3-30 MHz) are commonly used in long-range communication applications or in radars that require long-range detection capabilities. This is due to the refraction of HF radio waves, where the transmitted wave bends back towards to the Earth.
