Solving the problem of coexistence of primary and secondary users in the frequency environment with quasiorthogonal frequency access on subcarrier frequencies

Abstract

It is described the principles of implementing the method based on quasiorthogonal frequency access on subcarrier frequencies. The key element of quasiorthogonal frequency access on subcarrier frequencies is the using of the individual distribution of frequency subcarriers in different frequency plans of the ensemble in the general frequency band, which allows increasing the subscriber capacity of the radio system significantly.
