Abstract:
1. A communication circuit, comprising: first and second radio frequency (RF) transceivers, configured to down-convert first and second RF signals for a multiple-input and multiple-output (MIMO) technology; a third RF transceiver, configured to down-convert a third RF signal for a second telecommunication technology; a first baseband transceiver, coupled to the first RF transceiver, configured to digitize the down-converted first RF signal to output a first baseband signal; a second baseband transceiver, coupled to the second and third RF transceivers, configured to digitize one of the down-converted second or third RF signals according to a selection signal to output a second baseband signal; a first modem circuit, coupled to the first and second baseband transceivers, configured to digitally process the first and second baseband signals using the MIMO technology; and a second modem circuit, coupled to the second baseband transceivers, configured to digitally process the second baseband signal using the second telecommunication technology.
