Method of processing received digitized signals and mobile radio communication terminal device

摘要

A mobile radio communication terminal device may include at least one circuit configured to perform a method of processing received digitized signals, the method including determining a plurality of cross-correlation coefficients for the received digitized signal. Each of the plurality of cross-correlation coefficients may be determined by cross-correlating the received digitized signal with a respective candidate mobile radio local reference signal out of a plurality of pre-stored candidate mobile radio local reference signals. The at least one circuit may be further configured to select one or more cross-correlation coefficients from the determined plurality of cross-correlation coefficients and perform a mobile radio cell scan based on one or more of the selected cross-correlation coefficients, thereby determining a mobile radio communication network to connect to.

1. A mobile radio communication terminal device, comprising at least one circuit configured to perform a method of processing received digitized signals, the method comprising:
determining a plurality of cross-correlation coefficients for a received digitized signal, wherein each of the plurality of cross-correlation coefficients is determined by cross-correlating the received digitized signal with a respective pre-stored candidate mobile radio local reference signal out of a plurality of pre-stored candidate mobile radio local reference signals and wherein at least two of the pre-stored candidate mobile radio local reference signals are pre-rotated to be centered at different predefined carrier channel center frequencies; selecting one or more cross-correlation coefficients from the determined plurality of cross-correlation coefficients; and performing a mobile radio cell scan based on one or more of the selected cross-correlation coefficients to connect to a mobile radio communication network.
