[29] In addition, the dual transmission / reception frequency supply unit 300 may be connected to the first transmission / reception signal processing unit 100 and the second transmission / reception signal processing unit 200, respectively, so as to perform modulation and demodulation of RF signals during transmission and reception. It serves to supply different RF local frequencies, respectively, the first transmission and reception frequency supply unit 310 and the second transmission and reception frequency supply unit
[30] It consists of 320. At this time, the first transceiver frequency supply unit 310 and the second transceiver frequency supply unit 320 supplies the same RF local frequency to the first radio frequency transmitter 120 and the second radio frequency transmitter 220, respectively. It also provides multi-FA capability by providing different RF local frequencies while providing receive diversity.
[31] In addition, the first transmit / receive frequency supply unit 310 of the dual transmit / receive frequency supply unit 300 is connected to the first radio frequency transmitter 120 and the first radio frequency receiver 130 to perform modulation and demodulation of the RF signal.

The processor 200 supplies IF local frequencies so that the transmission signal received from the control station can be modulated into an IF signal.
[34] Next, an operation process of a transceiver supporting continuous / discontinuous multi-FA according to an embodiment of the present invention having the above configuration will be described with reference to FIG. 2.
[35] First, the RF local frequency supplied from the dual transmission / reception frequency supply unit 300 to operate the multi-FA transceiver of the present invention is different from the first transmission / reception signal processing unit 100 and the second transmission / reception signal processing unit 200. Local frequency is supplied.

By doing so, the transmit diversity function is performed.
[43] Meanwhile, in the case of reception diversity, the first RF receiver 130 receives an RF signal from the terminal through the first antenna 110, and at the same time, the second RF receiver 230 and the second antenna 210 are received. Through the first radio frequency receiver
[44] 130 receives the same RF signal.
[45] Then, the first RF receiver 130 demodulates the RF signal received through the first antenna 110 into a received signal through an RF local frequency supplied from the first transmit / receive frequency supply unit 310 and transmits the received signal to the control station. At the same time, the second RF receiver 230 also receives the same RF signal through the second antenna 210 and receives the first RF signal from the second transceiver frequency supply unit 310 from the second transceiver frequency supply unit 320. The RF signal is supplied with the same RF local frequency as the RF local frequency supplied to the RF receiver 130 to demodulate the RF signal into a received signal and then transmit the received RF signal to the control station. That is, as described above, one transceiver performs the transmit / receive diversity function.
[46] As described above, according to the transceiver supporting the continuous / discontinuous multi-FA according to the present invention, when expanding from the base station to the multi-FA, it is possible to secure not only excellent scalability but also expansion compared to a base station equipped with a conventional transceiver. There is an excellent effect to reduce the cost.
