摘要:
A wireless communication device (100) including a high-speed data buffer coupled to a first transceiver by a bus, and an application processor having a data buffer associated with the application processor. The associated data buffer is coupled to a high-speed data buffer and to a second transceiver by the bus, wherein the application processor is configured to control the transfer of data between the associated data buffer and the high-speed data buffer and to control the transfer of data between the associated data buffer and the second transceiver.
摘要:
A method and apparatus for detecting a frequency band and mode of operation using recursive sampling and narrowing down is disclosed. The method comprises sampling (215) by a multi-mode wireless communication device, a broad operational frequency spectrum at a first sampling rate to produce a first set of discrete signal samples. Then, the wireless communication device compares (230, 240) at least one of the energy graphs of the first set of discrete signal samples with at least one protocol-specific signature to confirm (245), if an approximate match is found. When one or more approximate matches are found, the wireless communication device narrows down (250) the broad frequency spectrum to a reduced set of frequency band(s) that correspond to the matched protocol-specific signature(s). Then the steps of sampling (215), comparing (230, 240), confirming (245), and narrowing down (250) are recursively followed till a frequency band and mode of operation is confirmed.
