Abstract
This article compares three open-loop suppressed-carrier acquisition techniques that are being considered for the Advanced Receiver II (ARX II). The algorithms (full-, half-, and staggered-symbol integration) employ fast Fourier transforms (FFTs) to detect the carrier-frequency offset in the presence of symbol-timing errors. Expressions for the detection probability of the frequency offset as a function of both the symbol signal-to-noise ratio (SNR) and constant symbol-timing errors are derived, and it is shown that the staggered-symbol integration technique has the best performance at low received symbol SNR, making it the preferred implementation for Deep Space Network applications.
