| description | In the article, 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. It was developed an algorithm for the formation of the ensemble, taking into account the different values of the width of the subchannels in the corresponding frequency plans. It was graphically represented the form of frequency plans with different bandwidths and the dependence of the maximum emissions of the mutual correlation function of frequency plans, taking into account the number of subcarriers and the width of subchannels. For realization the statistical analysis, it was constructe an imitation model of the radio channel, it were graphically represented the results of statistical analysis of the interrelationship properties of frequency plans, and investigated the correlation properties of complex signals based on QOFDM. Using the quasiorthogonal access on subcarrier frequencies allows increasing the subscriber capacity of the communication system and the rate of information transmission due to the nonlinear distribution of the subcarrier frequencies. |
