Recently, some low data rate unicast, multicast, or broadcast services, especially those provided by machine type communication (MTC), has drawn much attention. The main concern for the deployment of those MTC services is the receiver cost and the service coverage. Binary coding has been proved to be a promising technique to extend the base station coverage by recovering lost packets. In order to pull in the receiver cost, a low cost wireless broadcast receiver is used which uses less number of buffer to decoded the coded packets. In this work, we revisit the binary codebook design problem for low cost receiver by mainly focusing on the broadcast system where different group of users suffer from different packet loss probabilities. Simulation results show that our newly designed codebook can sustain a good portion of coding gain for broadcast system with the low cost receiver.
