Description
Technical field
The present invention relates to signal and close road and distribution technique, espespecially one realizes CF signal and closes road assigned unit and method.
Background technology
At frequency division communication field, it is often necessary to transmit two or more CF signals in a kind of communication channel such as microwave channel. CF signal is signaled by carrier frequency and the carrier frequency collection of letters number forms. Carrier frequency signals mainly to be signaled by the business after the service signal of sending side is modulated the modulation obtained on carrier frequency and forms. The frequency band that carrier frequency signals includes the frequency band that business is signaled and the guard band isolated for frequency band. The carrier frequency that the carrier frequency collection of letters number sends over for communication opposite end signals. The frequency band of CF signal includes carrier frequency signalling and the frequency band of the carrier frequency collection of letters number.
Fig. 1 realizes double; two CF signal to close roads assigned unit in existing microwave communication, in Fig. 1, f1 sends out and signals with the f1 carrier frequency receiving in respectively CF signal f1 and carrier frequency is collected mail number, and the rest may be inferred, it is known that the implication that f2 sends out and f2 receives. Respectively from the sending direction of device as shown in Figure 1 and reception direction, f1 sends out and sends out through each self-corresponding duplexer with f2, realizes closing road then through closing road/allotter, and the signal after finally closing road is sent by antenna; The f1 that includes from antenna receives and the signal of f2 receipts, the two paths of signals including f1 receipts and f2 receipts respectively through closing road/allotter to be distributed into, then obtains f1 receipts and f2 receipts respectively through duplexer.
In microwave communication, it is achieved it can be balance 3dB combiner and non-equilibrium 6dB combiner that two carrier frequency closing road/distribution of two CF signals close road/allotter. For balance 3dB combiner, in two branch port is about 3.8dB to the insertion loss closing road port, and reverse insertion loss is also 3.8dB. For non-equilibrium 6dB combiner, a branch port is about 7dB to the insertion loss closing road port, and another branch port is about 2dB to the insertion loss of conjunction road port, reverse insertion loss also respectively 7dB and 2dB.Being not difficult to find out, two carrier frequency close road/allotter when the conjunction road/distribution realizing two CF signals, introduce no small insertion loss.
General Communication Model in communication always can be attributed to most basic point-to-point communication. The system gain of product is depended primarily on for point-to-point wireless communication, transmission range and transmission capacity. System gain is the difference of the receiving sensitivity of the transmitting power of the one end in communication two ends and the other end. System gain is more big, and the transmission range of point-to-point communication and transmission capacity are more big, say, that ability to communicate is more strong.
In existing microwave communication as shown in Figure 2, double; two CF signals close the communication system of road/distribution, if communication two ends all adopt balance 3dB combiner, the insertion loss that balance 3dB combiner introduces makes the system gain of communication system as shown in Figure 2 decline about 7.8dB. In this communication system, if communication two ends all adopt non-equilibrium 6dB combiner, correspondingly system gain declines about 8dB. It is not difficult to find out, close in the communication system of road/distribution at two CF signals, the existing mode realizing closing road/distribution by closing road/allotter, reduce the system gain of communication system, therefore the ability to communicate of communication system is reduced, thus reducing transmission range and transmission capacity. Obviously, closing in the communication system of road/distribution at two or more CF signal, the existing mode realizing closing road/distribution by closing road/allotter reduces the ability to communicate of communication system larger.
