碩士 === 國立臺北大學 === 通訊工程研究所 === 102 === Binary coding is a promising technique for broadcast services by recovering the lost packets from additional coded packets. The current receiver requires additional buffer to store coded packets. However, in some real world communication systems, the receiver cost is the major concern. This work first proposes a low cost 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 coding gain so it remains a competitive scheme for communication systems aiming to provide broadcast service to low cost receivers.
