Phase Shift Key<strong>in</strong>g (PSK)- B<strong>in</strong>ary Phase Shift Key<strong>in</strong>g (BPSK) demonstrates better performancethan ASK and FSK.- PSK can be expanded to a M-ary scheme, employ<strong>in</strong>g multiple phasesand amplitudes as different states.- Filter<strong>in</strong>g can be employed to avoid spectral spread<strong>in</strong>g.
