                         modulation and non-coherent demodulation is widely used on the 
                         telecommand channel of the most TT\&C transceivers for CubeSat. 
                         However, this solution has low efficiency in terms of power. In 
                         this paper, a new all-digital AFSK modem is proposed. The 
                         demodulator uses the Viterbi algorithm to perform the maximum 
                         likelihood sequence detection (MLSD) and gives an expressive gain 
                         when compared to non-coherent detection. Original mathematical 
                         analyzes are presented to explain the proposed system. Some 
                         performance results, determined via computational simulation, are 
                         presented and discussed.",
