This letter presents a simplified expression for the average packet error rate (PER) for an uncoded packet transmission system with large packet length over slow Rayleigh fading channels, by assuming that the bit error rate (BER) has an exponential form. Then the throughput performance of an uncoded packet transmission system with automatic repeat request (ARQ) is investigated, and the optimal packet length is derived to maximize the throughput. The theoretical analysis is validated by simulations.read more

Packet Error Rate Analysis and Power Allocation for CC-HARQ Over Rayleigh Fading Channels
TL;DR: A novel approach is developed to evaluate the average packet error rate for chase combining (CC) based hybrid automatic repeat request (HARQ) protocol over block Rayleigh fading channels for the long packet system and it is found that the ratios among the optimal power sequence just depend on the targeted PLR and the maximum number of transmission rounds.

The throughput of hybrid-ARQ protocols for the Gaussian collision channel
Giuseppe Caire,Daniela Tuninetti +1 more
TL;DR: The throughput of automatic retransmission request (ARQ) protocols is compared to that of code division multiple access (CDMA) with conventional decoding and Interestingly, the ARQ systems are not interference-limited even if no multiuser detection or joint decoding is used, as opposed to conventional CDMA.
