Abstract
An apparatus for use in a relay wireless communication system is capable of bidirectional relaying with precoding. A Base Station (BS) includes a plurality of antennas. The BS can receive a relay signal that includes a transmit symbol vector of the BS and a transmit symbol vector of a Mobile Station (MS) from a Relay Station. The BS determines power difference values corresponding to all of symbol vectors available as the transmit symbol vector of the MS. The BS further determines the transmit symbol vector of the MS or per bit Log Likelihood Ratios using the power difference values.
