Abstract:
1. A two-way relay wireless communication apparatus for a wireless communication system, comprising: a transceiver, being configured to receive a relay receiving signal, wherein the relay receiving signal comprises a first terminal transmitting signal transmitted by a first wireless apparatus and a second terminal transmitting signal transmitted by a second wireless apparatus; and a processor electrically connected to the transceiver, being configured to use a mapping function to transform the relay receiving signal into a relay signal and enable the transceiver to broadcast the relay signal; wherein the mapping function is: where, α is a transmit power scaling factor, β is a phase rotation factor, x is the relay receiving signal, C is an offset, B is a modulus, and c mod(·) is a complex modulo function and is defined as follows: where x where A is an input signal and % is an asymmetric modulo operator defined as follows: p % q=p−└p/q┘q where p and q are any two real numbers and └p/q┘ means taking the largest integer smaller or equal to p/q.
