| Abstract(in English) | Physical layer network coding is well-known to improve frequency utilization efficiency in bi-directional wireless communication via a relay. This report proposes a novel error correction technique not only to improve transmission performance but also to reduce complexity at the relay. The proposed technique applies a unitary precoding to offset phase rotation of a channel gain by exploiting the reciprocity between channels in an uplink and a downlink in systems with time division duplex (TDD). The paper proposes a new maximum likelihood sequence estimation making use of the fact that the received signal can be regarded as a quasi-XOR coded signal by the channel. It is evaluated by computer simulation that the proposed technique attains a gain of 17dB at BER=10^<-5> in a system with the use of OFDM. |
