FIELD: radio engineering, communication.SUBSTANCE: invention relates to digital broadcasting which provides an audio indicator of link quality. After receiving a digital radio signal using a digital radio receiver, the quality of the received digital radio transmission is determined. Then an audio message from the received digital radio transmission is decoded. Then an audio indicator is superimposed onto the audio message, to form a composite audio signal. Finally, the amplitude of the audio indicator is dynamically adjusted relative to the amplitude of the audio message depending on the quality of the received digital radio transmission.EFFECT: improved quality of digital radio transmission of audio signals through accurate detection and correction of single-bit errors.26 cl, 5 dwg |
