Digital microwave relay systems interference calculation method
1 Scope
This standard gives the interference tolerance digital microwave relay communication system, the type of interference and interference calculation methods.
This standard applies to between 1GHz ~ 40GHz band, digital microwave relay systems and radar systems for digital microwave radio relay
Interfere with communications systems computing.
This standard is interference between digital microwave communication system mainly based on coordination and checking instruments, digital microwave communication system is generally provided
Design, construction and maintenance basis.
2 Normative references
The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent
Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research
Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard.

3 Terms and Definitions
The following terms and definitions apply to this standard.
3.1
Within an expected range of frequency stability, the same interference signal and the useful signal carrier frequency or interference generated when similar.
3.2
Since the adjacent channel sideband overwrite each other to produce interference.
3.3
Interfering station or interfering station antenna main beam central axis direction deviation angle between two stations connection (see Figure 9).
3.4
Due to selective RF and IF circuits, adjacent channel unwanted sideband attenuation in digital microwave systems.
3.5
Digital microwave channel a set of consecutive bits, each bit in the channel belongs to a block.
3.6
When one or more than one bit error occurs in a block, the block is called the block error.
3.7
In the 1s time, if there is one or more than one error block is said to sec errored seconds.
