13. HARQ Systems: Resource Allocation, Feedback Error Protection, and Bits-to-Symbol Mappings
Abstract : Reliability of data transmission is a fundamental problem in wireless communications. Fading in wireless channels causes the signal strength to vary at the receiver and this results in loss of data packets. To improve the reliability, automatic repeat request (ARQ) schemes were introduced. READ MORE
