Abstract
The utility model discloses a relaying digital exclave system, comprising a base station, a companding near-end machine and a companding far-end machine, wherein the base station is connected with the companding near-end machine through a coupler, the companding near-end machine and the companding far-end machine communicate with each other using a relaying wireless signal and respectively comprise two duplexers, and a downlink and an uplink both arranged between the two duplexers, the downlink and the uplink respectively comprise a low noise amplifier, a primary filter, a frequency converter, a secondary filter and a power amplifier, the low noise amplifier, the primary filter, the frequency converter, the secondary filter and the power amplifier are orderly connected, and a power supply module and a control module are connected between the two duplexers. The relaying digital exclave system is large in coverage range, is not easy to be influenced by extraneous environments, is small in wireless propagation path loss, enables signals to be uneasy to block, and is suitable to mountain area.
Description
Technical field
The utility model relates to a kind of digital enclave system, particularly a kind of relaying numeral enclave system.
Background technology
The rural area radio mobile communication utilizes the on-air radio channel to come communication; Because radio transmission receives the influence of topography and geomorphology atural object bigger; And the quantity of base station with the place be set receive certain restriction; Therefore in mobile communication network, have many wireless coverages blind area or wireless signal interference range, cause that the mobile subscriber can not insert, call drop or speech quality is poor.Numeral enclave system is that of network replenishes, and is under the outstanding situation of the primary problem that solves and capacity contradiction in covering, and digital enclave system can replace the base station and realize wireless coverage; But existing digital enclave system ovelay range is less; Telephone traffic is low, adopts primary frequency to transmit, and is subject to the external environment influence; The radio propagation path loss is bigger, and signal is hindered easily.
Summary of the invention
The purpose of the utility model just is to provide a kind of coverage bigger, is difficult for being affected by the external environment, and the radio propagation path loss is less, and signal is difficult for the relaying numeral enclave system that quilt is hindered.
To achieve these goals; The technical scheme that the utility model adopts is such: the relaying numeral enclave system of the utility model; Comprise base station, companding near-end machine and companding remote termination; The base station links to each other with companding near-end machine through coupler; Companding near-end machine and companding remote termination adopt the relay wireless signal communication, and companding near-end machine and companding remote termination include two duplexers and be arranged at down link and the up link between two duplexers, and said down link and up link include low noise amplifier, one-level filter, frequency converter, two-stage filter and power amplifier; Said low noise amplifier, one-level filter, frequency converter, two-stage filter are connected with power amplifier successively, also are connected with power module and control module between two duplexers.
Compared with prior art, the advantage of the utility model is: this system's diffracting power is strong, and loss is little, long transmission distance; It is high to save the frequency resource availability of frequency spectrum, and distortion rate is low in the signals transmission, and antijamming capability is strong; Avoided with interference frequently, but omnidirectional's covering, and coverage effect is good.
Description of drawings
Fig. 1 is the functional block diagram of the companding near-end machine of the utility model;
Fig. 2 is the functional block diagram of the companding remote termination of the utility model.
Embodiment
To combine accompanying drawing that the utility model is described further below.
Referring to Fig. 1 and Fig. 2; The relaying numeral enclave system of the utility model; Comprise base station, companding near-end machine and companding remote termination; The base station links to each other with companding near-end machine through coupler; Companding near-end machine and companding remote termination adopt the relay wireless signal communication, and companding near-end machine and companding remote termination include two duplexers and be arranged at down link and the up link between two duplexers, and said down link and up link include low noise amplifier, one-level filter, frequency converter, two-stage filter and power amplifier; Said low noise amplifier, one-level filter, frequency converter, two-stage filter are connected with power amplifier successively, also are connected with power module and control module between two duplexers.
This system's diffracting power is strong, and loss is little, long transmission distance; It is high to save the frequency resource availability of frequency spectrum, and distortion rate is low in the signals transmission, and antijamming capability is strong; Avoided with interference frequently, but omnidirectional's covering, and coverage effect is good; Power subsystem is that system provides power supply, and control unit is that prior art can realize various control to system.
