SLOKA describes BPSK as the simplest form of phase shift keying that uses two phases separated by 180 degrees. In BPSK, it does not matter where exactly the positions of the castellation points are, and they are always s... More »

The main advantage of phase shift keying is that it allows data to be carried along a radio communications signal much more efficiently than with frequent shift keying. PSK is a digital modulation scheme that transports ... More »

Frequency Shift Keying, or FSK, is a modulation technique that transmits digital signals over telephone lines, cables, optical fiber or wireless media. FSK data consist of two binary states, 0 and 1, represented by two d... More »
