We consider a base-station broadcasting a set of order-insensitive packets to a user population over packeterasure channels. To improve efficiency we propose relayaided transmission using instantaneously-decodable binary network coding. The proposed coding schemes have the benefits of minimal decoding delay and low complexity. We further analyze the performance of the resulting broadcast schemes, and show that significant improvements in transmission efficiency are obtained as compared to
