摘要： A method and apparatus for synchronizing a system clock with a serving cell (102) associated with a first radio access technology and monitoring an adjacent cell (104) associated with a second radio access technology is provided. A communication device (100) includes a first synchronization device (205) capable of synchronization with the serving cell (102) and a second synchronization device (206) capable of independently synchronizing with the adjacent cell (104). The first synchronization device (205) and second synchronization device (206) include independent frequency correction modules (207,208). Thus, the second frequency synchronization device (206) may be corrected per the adjacent cell (104) while the first synchronization device (205) remains synchronized with the serving cell (102). Thus, the same corrected system clock may be used between two radio access technologies.

摘要： A method and apparatus mitigates spurious transmissions. An offset local oscillator signal is generated that is at a frequency that is offset from a nominal transmit channel carrier frequency by a spurious mitigation offset. An information signal is generated that comprises a series of modulation symbols and has a transmission bandwidth at baseband. A configured offset information signal is generated from the information signal, wherein the spectrum of the configured offset information signal is offset from DC by a channel configuration offset, and is further offset by a negative of the spurious mitigation offset. The offset local oscillator signal and the configured offset information signal are combined using a mixing technique. The spurious mitigation offset is zero when a spurious condition does not exist and is non-zero when the spurious condition does exist.

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.
