8-Phase phase-shift keying demodulator. |
摘要 |
<p>In order to rapidly bring a 8-phase phase shift keying demodulator into resynchronization upon the demodulator going out of synchronism, a plurality of error signals produced within the demodulator is used to determine whether a signal point of an incoming 8-phase phase modulated signal is usable for controlling a transversal filter. An asynchronism signal, which indicates whether the demodulator is synchronized, is derived from the demodulator and being applied to a tap gain control signal generator coupled to the transversal filter. The tap gain control signal generator is controlled when the asynchronism signal indicates asynchronism of the demodulator.</p> |
