Abstract:
1. A method for tuning a Single Sideband receiver to receive signals at a desired frequency, comprising: obtaining an audio signal at the receiver, the audio signal being received at a first frequency; processing the obtained signal in a time domain via a first processing unit associated with the receiver; converting the obtained signal to a frequency domain via a first conversion unit associated with the receiver; processing the signal converted into the frequency domain to further modify the signal via a second processing unit associated with the receiver and thereby form a modified signal; converting the modified signal from the frequency domain to a correlation domain via a second conversion unit associated with the receiver; processing the converted, modified signal in the correlation domain via a third processing unit associated with the receiver to thereby obtain a processed signal; analyzing the processed signal from the correlation domain via an analysis unit associated with the receiver to determine a receiver tuning error; and retuning the receiver to obtain audio signals at a second frequency derived from the first frequency adjusted based on the determined receiver tuning error.
