Analysis of tracking performance of the MTDD Costas loop for UQPSK signalThe tracking performance of the breadboard Costas loop for the Multimegabit Telemetry Demodulator/Detector (MTDD) System using an unbalanced quadriphase-shift-keyed (UQPSK) signal is considered. The particular Costas loop is a biphase polarity type with passive arm filters. The loop contains a hard limiter in front of the third multiplier, which is a chopper-type device. The rms phase jitter predictions made have also been verified experimentally.
