Intersymbol interference and additive noise are two common sources of distortion in data transmission systems. For pulse amplitude modulation (PAM) communicatio ...

But for a weekend project, [Vinod.S] took the ultrasonic transmitter and receiver from a distance-meter module and used amplitude modulation to send music ultrasonically from his laptop to a ...

We previously proposed a set-partitioning 64APSK coded modulation as a scheme of expanding transmission capacity for satellite broadcasting. Conducting transmission-performance evaluations with a ...
