Delay Analysis for TDMA Schemes with Packet Recombining
Résumé
This paper considers the use of SC modulations
(Single-Carrier) with FDE (Frequency-Domain Equalization) with
low-complexity soft combining ARQ schemes (Automatic Repeat reQuest).
With our technique, packets associated to different transmission
attempts are combined in a soft way, allowing improved performances. Its
low complexity makes it particularly interesting for the uplink of
wireless systems. This paper proposes an accurate analytical model for a
TDMA (Time Division Multiple Access) scheme where packet combining ARQ
is applied. It evaluates the uplink non-saturated packet delay for a
generic message arrival process. Our analytical results are validated
using physical and MAC layer simulations.
