  • Patent number: 10813014
    Abstract: A radio network device, having a narrowband receiver and operative in a wireless communication network, exploits the periodicity of transmission of network sync signals by iteratively receiving a plurality of frequency-offset portions of the sync signal, and then assembling the portions to recreate the entire sync signal. The recreated sync signal is then processed to attempt network detection and synchronization. In some embodiments, frequency/time compensation may be applied to the received and stored sync signal portions, prior to their combination, to compensate for uncertainty in the frequency drift (and time drift due to frequency error) of the sync signal location.
