Estimation of Desynchronization Parameters of Receiving-Transmitting Devices in System with Orthogonal Frequency Condensation

Principal of desynchronization in system using orthogonal frequency-division multiplexing are investigated. The optimum algorithm of time and frequency mismatches estimation by criterion of maximum likelihood in time area is developed. Quasi-optimum algorithm of estimation is offered, the block diagram of synchronization is constructed. With help of imitation modeling the basic statistical characteristics of mismatches are received, optimization of the circuit is made.
