Embodiment 1
[0052] An embodiment of the present invention provides a method for combining adjacent frequency systems, and the execution subject is a combiner, such as figure 2 As shown, the method includes the following steps:
[0053] 101. Determine the minimum isolation bandwidth required for combining the first communication system to be combined with the second communication system, the protection bandwidth of the first communication system, and the protection bandwidth of the second communication system; according to the minimum isolation The bandwidth, the guard bandwidth of the first communication system, and the guard bandwidth of the second communication system calculate a frequency offset value.
[0054] It should be noted that the first communication system and the second communication system are two different wireless communication systems, and the allocated frequency bands of the two are different and the allocated frequency bands are adjacent. The so-called isolation bandw...
Embodiment 2
[0090] An embodiment of the present invention provides an adjacent frequency combiner, such as Figure 10 As shown, the adjacent frequency combiner includes: a combining unit.
[0091] a combining unit, configured to use the bandwidth between the combining cutoff frequency of the first communication system and the combining cutoff frequency of the second communication system as the isolation bandwidth between the first communication system and the second communication system to perform the the combination of the first communication system and the second communication system;
[0092] Wherein, the combined cutoff frequency of the first communication system and the combined cutoff frequency of the second communication system are based on the frequency offset of the first communication system and the frequency offset of the second communication system And determined by adjacent frequency points between the first communication system and the second communication system; the frequ...
