In our previous work, a time efficient data retrieval method was proposed for distributed data sources using the generalized group testing approach. In this work, we provide the physical-layer transmission and reception strategy that supports the implementation of the group testing method. The integration of the two protocols leads to a modified strategy that incorporates the errors occurring within the feedback channel. We propose a signal modulation scheme combined with the source and channel coding that was proposed using the concept of group testing. The numerical simulations show an improved performance with the proposed cooperative broadcasting scheme. Our methodology does not separate channel and source coding and can be implemented with a two layer architecture with low complexity.
