  • Publication number: 20150024791
    Abstract: A wireless communication device is disclosed that is capable of performing efficient network searching. Specifically, by utilizing its location information and accessing stored cell information, the device can streamline searching. Further, if a full search is to be performed, the device receives information from multiple radio access technologies together, and processes the received information digitally in order to search the individual radio access technologies. In addition, the device is capable of performing efficient 4G searches by setting its RF module to capture information of multiple raster points simultaneously within a search band, and shifting the search band so as not to duplicatively search raster points.

  • Publication number: 20140241447
    Abstract: A user equipment (UE) performs a transform domain (DFT) based method to detect the cyclic prefix (CP) length that is being used by a base station for cellular communications. The detected CP length is then used to reduce the amount of time required to complete the synchronization and cell search procedures. In particular, the UE uses the detected CP length information to obtain Cell Identification parameters (NID1, NID2) along with information including a Maximum energy Tap location and a reference signal receive power (RSRP) while completing the synchronization and cell search procedures.

  • Publication number: 20130129006
    Abstract: A transmitter including a signal generator to generate an analytic signal in frequency domain, having frequency components that when converted to time domain result in a time domain signal with a preamble that includes a first half of containing non zero information and a second half containing only zero data. A shaper configured to generate a cyclic prefix including only zero data based on the second half of the preamble included in the time domain signal, and to attach the cyclic prefix including only zero data to the time domain signal to output a pilot signal that is to be transmitted via an antenna.

  • Publication number: 20130129007
    Abstract: A method including receiving a received signal in time domain and obtaining a cyclic prefix (CP) correlation on the received signal, the CP correlation including spectral components associated with a plurality of possible cyclic prefix lengths; converting the obtained CP correlation to frequency domain; distinguishing spectral components associated with a first cyclic prefix length from spectral components associated with a second cyclic prefix length; calculating a first metric based on the spectral components associated with the first cyclic prefix length, and calculating a second metric based on the spectral components associated with the second cyclic prefix length; setting an order of cyclic prefix lengths based on a comparison of the first metric and the second metric with a threshold, the order including the first cyclic prefix length and the second cyclic prefix length; and completing a synchronization process based on the order of the cyclic prefix lengths.
