Abstract: The present disclosure provides a cleaning and recovery method and device for a heterogeneous executor in a mimic switch, and a mimic switch, the method includes: a mimic scheduler determining a designated heterogeneous executor that needs to be cleaned, marking the designated heterogeneous executor that needs to be cleaned as in a cleaning state, and sending a cleaning instruction to the designated heterogeneous executor; the designated heterogeneous executor sending a normal protocol negotiation message to the mimic scheduler to try to interact with the mimic scheduler; the mimic scheduler receiving the protocol negotiation message and detecting whether the designated heterogeneous executor is in the cleaning state; if in the cleaning state, the mimic scheduler; constructing a training message, and sending the training message to the designated heterogeneous executor for protocol training; repeating sending and processing the protocol negotiation message until the designated heterogeneous executor is in a n

Abstract: Disclosed are an IQ mismatch compensation method and apparatus for a radio frequency communication system, a compensation device and a communication device. The method comprises: acquiring an interaction result of test signals between a transmitting component and a receiving component; obtaining angle mismatch parameters of a pre-determined type according to the interaction result; determining a frequency domain compensator for performing mismatch compensation on the frequency-dependent angle mismatch parameters according to the following formulae: Y(w)=X(w)?jP(w)*X*(?w) and Y(?w)=X(?w)+jP(w)*X*(w); and performing frequency domain compensation on the frequency-dependent angle mismatch parameters by using the frequency domain compensator. Also disclosed is a computer storage medium.
