Abstract
A radio receiver including a memory storing a reference sample sequence and a synchronizer. The synchronizer receives a data packet, samples and modulates symbols from the data packet and then generates phase-information samples from the modulated samples. The phase-information samples are low-pass to generate a filtered phase-information sample sequence. Samples of the filtered phase-information sample sequence are selectively compared with samples of the reference sample sequence and bit synchronization is established when a selected number of samples of the filtered phase-information sample sequence match a selected number of samples of the reference sample sequence.
