Abstract
This article discusses open-loop frequency-acquisition performance for suppressed-carrier binary phase shift keyed signals in terms of the probability of detecting the carrier frequency offset when the arms of the Costas loop detector have one-pole filters. The approach, which does not require symbol timing, uses fast Fourier transforms (FFTs) to detect the carrier frequency offset. The detection probability, which depends on both the 3-dB arm filter bandwidth and the received symbol signal-to-noise ratio, is derived and is shown to be independent of symbol! timing. It is shown that the performance of this technique is slightly better than other open-loop acquisition techniques which use integrators in the arms and whose detection performance varies with symbol timing.
