Software Radio Receiver for Audio and Video Broadcasting Systems
As new sound and video broadcasting systems are being deployed, the need for a multistandard multiband receiver increases. The compatibility of the software radio receiver with any defined broadcasting service is guaranteed by its re-programmability, i.e. by the fact that its functionality is determined by software. A receiver for a new standard can be added by a simple software download. In this paper a software implementation of the signal path from the ADC to the audio/video output will be discussed. The possibility of software reuse in different receiver functional blocks and for different broadcasting standards will be investigated.
