Abstract
A method of receiving data signals having identical contents and different frequencies. The frequency position of the data signals is analyzed by means of an FFT, and the signals are down-converted to the same intermediate frequency. The frequencies are selected such that the partial waves are constructively superpositioned, thereby improving the signal-noise ratio in the sum.
