Abstract

The embodiment of the invention discloses a microwave transmission method, a device and a system applying CCDP and XPIC, which relate to the technical field of mobile communication, wherein the microwave transmission method comprises the following steps: sending two businesses which correspond to the same frequency point and have different directions of polarization, wherein the two businesses are paired into one logical group; when a fault signal sent by an opposite terminal is received by a feedback channel, turning off the sending of the business indicated by the fault signal. After the embodiment of the invention receives the fault signal sent by the opposite terminal, turning off the sending of the business indicated by the fault signal, and thereby, interference can not be created on the other business, and therefore, the correct reception of the other business is ensured.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a microwave transmission method, device and system applying CCDP (Co-Channel DualPolarization, co-channel dual polarization) and XPIC (Cross Polarization Interference Cancellation, cross polarization cancellation). Background technique [0002] With the development of communication networks, the demand for service bandwidth increases continuously, but the available frequency resources are limited. Under the same frequency resources, CCDP technology is one of the main means to increase transmission capacity. On the same frequency, CCDP technology can use two different polarization directions of horizontal and vertical to transmit two different signals at the same time, which can double the spectrum utilization. [0003] In the CCDP system, due to multipath fading, non-uniform layer and ground scattering, the influence of rain and fog, etc., and the limitation of the ma...
