<p>A method for the reception in cooperative communication is disclosed by the embodiments of the invention, wherein the method includes: demodulating the received signal transmitted by a first source end to obtain a first log-likelihood ratio; demodulating the received signal transmitted by a second source end to obtain a second log-likelihood ratio; demodulating the received signal transmitted by a relay node to obtain a third log-likelihood ratio, wherein the signal transmitted by the relay node is the signal generated by network coding on the signal transmitted by the first source end and the signal transmitted by the second source end; according to the exclusive-or characteristic of the network coding, processing the first, the second and the third log-likelihood ratios to obtain a posterior log-likelihood ratio of the first source end; decoding the received signal transmitted by the first source end using the posterior log-likelihood ratio of the first source end. An apparatus and a system for the reception in cooperative communication are also disclosed by the embodiments of the invention. With the above technical solutions, the network coding is fully used to obtain the diversity gain, and the system performance is upgraded.</p> |
