| Summary |
One technique to provide high data transmission for
large number of users in mobile cellular networks is to arrange
the network in a multi-hop structure. Multi-hop networks have
large channel capacity and can achieve multi-route transmissions.
When the information bit streams are transmitted over multiple
routes, a route diversity effect would also be possible. In
multiroute transmission, we usually require the routing protocols
which can make every route condition be equal. The requirement,
however, makes the routing algorithm be complex and causes
large power consumption. Forward error correction schemes and
turbo coding can be far from the strict requirement although
they enhance the effect of route diversity. When applying the
turbo codes, the receiver should know the channel condition
for iterative decoding. Thus we have to consider how to obtain
the channel information over the multi-route multi-hop network.
Furthermore, the performance would improve when the destination
knows the difference of the route reliability. In this paper, we
propose the turbo coded multi-route multi-hop networks using
parity check bits. By using parity bits, we can easily estimate the
channel information in multi-route multi-hop networks. Using
numerical examples we show that the proposed scheme improves
the performance in additive white Gaussian noise and slow fading
channel conditions. |
