Abstract (in Japanese) (See Japanese page) 
(in English) A relay scheme combining network coding with channel
coding is proposed for multiple-access relay channel. Via a
newly designed network low density parity check code, this
scheme permits the relay node to jointly encode the data
information from two source nodes. To predict the system
performance, a newly generalized Gaussian Approximation
algorithm is derived, based on which an optimization algorithm
is developed to search the degree distribution of the
network LDPC code. Simulations show that, in a network
with two sources, one relay and one destination, the system
with the designed network low density parity check code
hold a performance gap less than 0.6dB from the threshold
and a performance gain of about 0.3dB can be achieved to
the same rate XOR network coding scheme at BER=10¡5.
