Optimization of large sensor network architecture in order to improve the overall
system performance at the end processing station is an important challenge. Many architectures
have been designed to optimize the bit error rate. Conventionally, this optimization
is performed by inserting relays between sensors and destination. These relays insert
redundant information by mixing the incoming streams from sensor nodes hence creating
parity check information which is very useful to help decode the transmit information
from sensors. The goal is to combine network and channel coding to match network on
graph to code on graph, and this is called adaptive network coded cooperation. Compared
with the previous works in the field, we propose a new transmit protocol based on
the use of beamforming technique, which is very efficient in terms of throughput and
is fully compatible with the physical network coding (PNC) principles. Furthermore,
we propose a distributed coding scheme where the relay, the destination, and the sensors
are all equipped with repeat accumulate (RA) channel code structures. The relay has
a special RA structure to suit the need of the PNC multiple‐access channel. Copyright
