Abstract
Two algorithms for frequency error detection in OQPSK satellite modems are presented. The results of computer simulations in respect of acquisition and noise performance are given. These algorithms are suitable for DSP implementation and are applicable to mobile satellite systems in which significant Doppler shift is experienced.
