Abstract:
1. A multi-standard transceiver comprising: a first subunit configured to perform signal processing according to a first communication standard; a second subunit configured to perform signal processing according to a second communication standard; and an interference cancellation unit configured to derive an estimated interference signal from a first signal generated by the first subunit by performing the signal processing according to the first communication standard, and perform interference cancellation on a second signal generated by the second subunit by performing the signal processing according to the second communication standard based on the estimated interference signal; wherein the interference cancellation unit is configured to derive an echo transfer function describing a leakage of the first signal into the second signal in a baseband of the first subunit, derive the estimated interference signal based on the echo transfer function, and subtract the estimated interference signal from the second signal in a baseband of the second subunit.
