Testing of channel coefficients of MIMO communication system in the presence the set of interferences

In this paper produced effect investigation of thermal and phase noise of frequency synthesizer complex on error of MIMO channel coefficients estimation. Dependence of channel coefficients estimation errors on time mismatch when channel coefficients testing is analyzed. Employment of technique time-division multiplexing is justified. Calculated to dependencies of error estimation on accepted signal counting number. Comparing results of simulation and experimental is carried out, their good agreement is shown.
