Resource allocation and block coding within a three-stage collaborative broadband relay network
conference contribution
posted on 2009-09-29, 15:23 authored by Shakiru K. Kassim, Nasr E.M. Eltayeb, Jonathon ChambersIn this work we propose a power control algorithm
for a multi-input multi-output orthogonal frequency division
multiplexing (MIMO-OFDM) multi-hop collaborative relaying
network. Using orthogonal and quasi-orthogonal block codes
with three stage processing our algorithm optimally distributes
available transmission power based on the architecture and
the channel condition at each stage so as to minimize the
end-to-end bit error rate (HER) of the entire relay network.
For high data rate applications with maximum throughput (as
expected for future OFDM systems), we employ a regenerative
relaying process, where the relays at each stage decode and
through collaborative processing, re-encode the received data
before onward transmission to the next stage and then to the
destination.
We provide simulation results 1 that confirm the performance
improvement in the end-to-end bit error rate (HER) of the network
using our explicit power allocation algorithm as compared
with equal power distribution technique.
