Abstract :
Superposition coding can be used to improve capacity of communications in a variety of scenarios. This paper is concerned with the application of superposition coding in TDMA system forward link packet data transmission with adaptive modulation and coding (AMC). By taking advantage of the total received SINR disparities on the forward link, the system can transmit to multiple users at the same time and frequency by using superposition coding. The average sector throughput of TDMA system forward link packet data transmission with the proposed superposition coding technique is mathematically analyzed for a multi-cell scenario. From numerical examples, it is shown that superposition coding can significantly increase the average throughput of the system.
