Abstract:

A broadcast system with ACK/NAK feedback is considered where each link is modeled as a Rayleigh fading channel. The performance improvement is investigated if the erroneously received packets are not discarded and the soft information within them is exploited to reduce the number of transmission attempts. An outer bound on the packet reception rate region on the physical layer is provided by extending that region on the packet layer. A new transmission algorithm is proposed that combines log-likelihood ratios on the physical layer with network coding. This transmission algorithm does not require the transmitter to know any prior or instantaneous information about the channel and considers network coding on both the packet layer and the physical layer. Simulations show that the transmission algorithm with soft decoding achieves rates close to an outer bound for the packet reception rate region.
