Abstract: An experiment in transmitting speech by Pulse Code Modulation, or PCM, is described in this paper. Each sample amplitude of a pulse amplitude modulation or PAM signal is transmitted by a ...
First, we conduct the theoretical analysis of the amplitude modulation (AM) mechanism in continuous-wave (CW) Doppler radar sensors. Our study reveals that in the presence of transmit (TX)–receive (RX ...
Out of these the most popular one used in a wireless transmission is digital modulation. The popular Digital modulation techniques are Amplitude Shift Keying, Frequency Shift Keying, Phase Shift ...
