Modem data transmission method for TDMA radio system

摘要

The data transmission method has an analogue output signal (Sa) from a modem (MOD) converted at the transmission side into a digital signal (S'd) for transmission via a modulated HF signal, with extraction of the digital signal at the reception end for conversion back into an analogue signal. The analogue output signal is converted directly into the digital signal using an adaptive prediction coding (COD), with a corresponding adaptive prediction decoding (DEC) used as the reception end for direct conversion of the received digital signal into an analogue signal, the transmitted digital signal divided between at least 2 time slots.
