Abstract
A self-adaptation method for optimizing multiple communication modules coexisting in frequency-division duplexing is provided. The method is operated in a communication system having at least two communication modules. Communication data generated by the communication modules is obtained when the communication system is operated under a time-division duplexing mode. The communication data is used to establish a standard comparison value for a frequency-division duplexing mode. The communication system then enters a parameter-adjustment phase, and radio-frequency parameters for the communication modules can be obtained. Thus, based on the standard comparison value, key performance indicator check is periodically performed for assessing whether to start or to stop a frequency-divisional duplexing training process according to one or more reference indicators so as to determine whether the radio-frequency parameters need to be adjusted. A set of radio-frequency parameters suitably operating the communication system under the frequency-division duplexing mode are finally obtained.
