ABSTRACT:
A radio frequency (RF) transmission correction module includes an RF transmission error detection module and a correction module. The error detection module includes an RF envelope detector, a signal conversion module, and an error detection module. The RF envelope detector is operably coupled to produce an envelope signal from a transmit RF signal, wherein the envelope signal represents at least one of local oscillation leakage and in-phase (I) and quadrature (Q) imbalance. The signal conversion module is operably coupled to convert the envelope signal into an error signal in accordance with baseband processing of the transmit RF signal. The error detection module is operably coupled to determine at least one of a local oscillation leakage value and an I and Q imbalance value from the error signal. The correction module is operably coupled to produce at least one of a local oscillation leakage correction signal and an I and Q imbalance correction signal based on the at least one of the local oscillation leakage value and the I and Q imbalance value, respectively.
