Abstract: |
For hybrid ARQ system with bursting errors, an effective method
to estimate amounts of optimized sub-packet and an adaptive sub-packet transmission solution are proposed for high speed data communi
cation. The simulation verification for adaptive sub-packet tran
smission solution′s performance is given based on the theoretical analysis of o
ptimized amounts of sub-packet. Simulation results
show that the adaptive sub-packet transmission solution can effectively im
prove the system throughput to the best according to different channel state in dynamic channels. |
