Spatial signal processing with QAM-M modulation efficiency research for microwave link

The analysis of experimental investigation of spatial signal processing of a microwave band for a signal-of-interest with modulation QAM-M extraction (M=64, 128, 256) from a wanted signal radiation source against interference from another radiation source for the case when bands and polarization type are the same, but the radiation source angular position is different, are presented. These results can be helpful for designers of microwave devices and microwave systems, such as radio relay systems.
