Abstract

The paper reviews a method of demodulation using integrators. In order to realize this method, the receiver requires two ways to synchronize the received signals, i.e., methods for achieving optimum synchronization of the integration time position and of the integration time length. Synchronization of the integration time position is realized by comparing the value of the integrators while shifting the integration time position. However, since the output of the integrator increases as the integration time length increases, the synchronization of the integration time length cannot be realized simply through comparison. The paper devises a method of comparison to realize synchronization whereby the average value of the integrator output of three integration time lengths, that have the relationship between 1/2 fold, 1 fold and 2 fold, is multiplied by a specific coefficient.
