Network Coding Design for Broadcast Service of Low Cost Receiver

Network coding is a promising technique for broadcast services by recovering the lost packets from additional coded packets. The current network coding receiver requires additional buffer to store coded packets. However, in some real world communication systems, the receiver cost is the major concern. This paper, first proposes a low cost network coding receiver, which reduces the receiver cost by removing the buffer for coded packets. Codebooks suitable for this low cost receiver are also designed. The simulation results show our low cost scheme preserves a large portion of the network coding gain so it remains a competitive scheme for communication systems aiming to provide broadcast service to low cost receivers.
