Signal synchronization, and 1 time slot that staggers in time between the two are received, link channel is thus effectively avoided with local letter
Interfering between road.The method of solution interference in the past is to increase the distance of channel transceiver antenna increases the isolation distance of antenna
Plus, the installation requirement of isolation is increased, by the distance of method of the present invention dual-mode antenna without the need for increasing, cost is reduced, and
Reduce the difficulty of installation.
Used as a kind of preferred version, the configuration of PDT Digital Clustering base station radio links channel frequency and the method for accessing also are wrapped
The relay base station for including PDT Digital Clusterings base station determines relay base station using the synchronization character of radio configuration signaling or using satellite time transfer
When base, make relay base station link channel receive signal it is synchronous with the link channel transmission signal of center base station, relay base station
Link channel transmission signal it is synchronous with the reception signal of the link channel of relay base station；The transmitting of the local channel of relay base station
The transmission signal of the link channel of signal and relay base station in time the local channel transmission signal of diversity, i.e. relay base station when
The link channel of relay base station is idle, the link channel transmission signal of relay base station when the local channel of relay base station is idle, in
It is synchronous with the local channel of relay base station reception signal after the local channel transmission signal of base station.
The transmission signal reception signal method of relay base station link channel and local channel is similar with center base station, and passes through
The synchronization character or satellite time transfer of RC signalings is synchronous with center base station, and the interference problem for making relay base station is also resolved.
Used as a kind of preferred version, relay base station adopts the local letter of reverse configuration wireless channel mode, i.e. relay base station
The local channel of road transmission signal and relay base station receives the sign of the frequency-splitting of signal and the link channel of relay base station
The link channel of transmission signal and relay base station receives the opposite sign of the frequency-splitting of signal.If local channel tranmitting frequency
Receives frequency apart from link channel is nearer, and powerful transmission signal easily affects the small-signal of frequency nearby, have impact on
Link channel receives the performance of signal.Communication relay base station makes local channel tranmitting frequency distance by the way of reverse configuration
The receives frequency difference of link channel is larger, greatly reduces interference, and the process of deployment of relay base station need not change, and be easy to
Quickly set up the process of relay base station.
Used as a kind of preferred version, the local channel transmission signal of relay base station and the link channel of relay base station receive letter
Number frequency-splitting be more than 10MHz.The difference design of 10MHz just makes high-power transmission signal not interfere with faint reception letter
Number.
The invention has the beneficial effects as follows, the configuration of PDT Digital Clustering base station radio links channel frequency and the method for accessing make
Signal channel launched will not dock the collection of letters number and produce interference, substantially increase communication efficiency, and less to the change of relay base station,
Beneficial to the rapid deployment of relay base station.
