  • System for simultaneous transmission of morse signalling over a radio communication using digital technology
    Patent number: 8891718
    Abstract: A system for simultaneous transmission (1) of Morse signaling over a radio communication using digital technology, comprising a signal generator (2) with at least one digital modulation which includes at least one amplitude modulation component; a Morse code generator (3) that generates Morse tones in analog form; and a first attenuator module (4), controlled by the Morse code generator (4). In this way, a signal with digital modulation generated by the signal generator (2) is attenuated in amplitude by the first attenuator module (4), the amplitude attenuation being the function of the amplitude of the waveform generated by the Morse code generator (3). In this way the transmission of information by digital modulation is simultaneous with the transmission of the Morse code by analog amplitude modulation (AM), using one single radiofrequency (RF) carrier signal and without service interruption or information loss.

  • Method for adapting radiofrequency signal spectrum
    Patent number: 8626140
    Abstract: Method for adapting radiofrequency signal spectrum, particularly in TETRA communications systems. The invention proposes using over-the-air signaling for communications systems according to the TETRA standard, to configure the characteristics of the radiofrequency signal, with the advantage that there is no loss of performance in data transmission speed and no need to change the type of modulation.
