In this embodiment, the first received signal filtered by the first pre- RX 201 and/or the second received signal filtered by the second pre- RX 202 are also required to pass through the low noise amplifier 401. The low noise amplifier 401 is an amplifier having a low noise figure, and is generally used as a high frequency or intermediate frequency preamplifier for various types of radio receivers, and an amplifying circuit of a high sensitivity electronic detecting device. In the case of amplifying a weak signal, the noise of the amplifier itself may be severely disturbed by the signal, so it is desirable to reduce this noise to improve the signal-to-noise ratio of the output.

Since the signal from the antenna is generally very weak, the low noise amplifier is generally located very close to the antenna to reduce the loss of the signal through the transmission line. This "active antenna" configuration is widely used in microwave systems such as global positioning systems because coaxial cables are very lossy in the microwave frequency range.

If the second received signal is allocated to the third rear RX 204 and the second rear RX 206, the second base transceiver station can receive the second received signal, and the first base transceiver station refuses to receive the second received signal. .

The power splitter 501 can split the energy of one input signal into two or more devices that output equal or unequal energy, or vice versa, and combine the energy of the multiple signals into one output. This can also be called a combiner. A certain degree of isolation should be ensured between the output ports of a power splitter 501. The power splitter 501 is also called an overcurrent splitter, which is divided into active and passive. It can evenly distribute one signal into several outputs. Generally, there are several decibels of attenuation per minute, the signal frequency is different, and the splitter is different. The attenuation is also different. In order to compensate for the attenuation, a passive power splitter is made after the amplifier is added.
