An electronic device for a wireless communication system is described. The electronic device comprises: a receiver configured to receive a modulated signal on a communication channel; and a processor, coupled to the receiver and configured to: process the received modulated signal; identify a communication channel characteristic based on the processed received modulated signal; select an equalizer having a first set of equalization coefficients based on the identified communication channel characteristic, wherein the first set of equalization coefficients is selected from a plurality of equalization coefficients, each of the plurality of equalization coefficients being associated with different communication channel characteristics; equalize the processed received modulated signal on the communication channel using the selected equalizer; and detect the equalized received modulated signal.

A method of configuring at least one frequency dependent (FD), in-phase/quadrature (I/Q), imbalance compensation filter within a radio frequency (RF) module is described. The method includes applying an input signal to an input of the RF module, receiving a filtered I-path signal for the RF module and deriving at least one I-path filtering estimate value therefrom, receiving a filtered Q-path signal for the RF module and deriving at least one Q-path filtering estimate value therefrom, and configuring the at least one FD I/Q imbalance compensation filter based at least partly on at least one ratio between the derived I-path and Q-path filtering estimate values.
