QPSK loop lock detection in the advanced receiver
Abstract
The Advanced Receiver (ARX 2) currently being developed uses a Costas crossover loop to acquire and track the phase of an incoming quadrature phase-shift-keyed (QPSK) signal. The performance is described for the QPSK lock detector to be implemented, taking into account the phase jitter in the tracking loop. Simulations are used to verify the results of the analysis.
