Influence of Active Interference on the Capacity of a MIMO-OFDM System Using an Adaptive Processing Algorithm

The influence of active interference on the bandwidth of a MIMO-OFDM communication system is studied using an adaptive signal processing algorithm in the receiver. Theoretical calculations of the features and characteristics of MIMO systems are presented, and a mathematical model for calculating the throughput of MIMO systems is presented. Experiments on signal detection in a communication channel with and without adaptation using the Viner criterion and the presence of interference with one type of modulation (QPSK) are presented. The results show that the adaptation allows us to achieve an increase in throughput along the entire line of the dependence curve and for all SNRs, even in the presence of interference.
