摘要： In a method in a common observation receiver of a transceiver, a Transmitter Radio Frequency, TXRF, signal spectrum is received, a Receiver Radio Frequency, RXRF, signal spectrum is further received. Furthermore, a switching scheme is determined based on whether the type of the transmitter and the receiver is Frequency Division Duplex, FDD, or Time Division Duplex, TDD. Based on the switching scheme, the TXRF signal spectrum and the RXRF signal spectrum are switched into a switched baseband signal spectrum. By arranging a common observation receiver in a radio transceiver, and observing radio frequency signal spectrums, the transceiver may acquire knowledge about nonlinearities and other irregularities of applied components.

摘要： A TDD radio unit and a real-time RX supervision method used therein are provided. The method comprises steps of: setting the radio unit into an RX supervision status in a TX timeslot, wherein the setting comprises: connecting a TX observation module in the radio unit to a termination port of a Transmit/Receive (TR) switch in the radio unit; and setting all components in the RX path in a power-on status; detecting a gain of the TX observation module by means of a signal from the TR switch passing through the TX observation module and a gain of the RX path by means of a TX leakage signal passing through the RX path; calculating a gain difference between the TX observation module and the RX path; and comparing the calculated gain difference with a preset gain difference to determine a state of the RX path. With the TDD radio unit and RX supervision method, the TX leakage signal is used, and thus no extra simulation source is need. Furthermore, a real time supervision is performed.
