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.
