A two-way relay, a wireless apparatus and a signal processing method thereof are provided. The two-way relay comprises a transceiver and a processor. The transceiver receives a relay receiving signal including a first terminal transmitting signal transmitted by a first wireless apparatus and a second terminal transmitting signal transmitted by a second wireless apparatus. The processor, which is electrically connected to the transceiver, uses a mapping function to transform the relay receiving signal into a relay signal and enables the transceiver to broadcast the relay signal. 1. A two-way relay 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; anda 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; {'br': None, 'i': f', 'x', 'c', 'x+C,B, 'sub': 'MF', '()=α·mod(β)'}, 'wherein the mapping function is {'br': None, 'i': c', 'x', '+jx', ',B', 'x', ',B', 'j', 'x', ',B, 'sub': I', 'Q', 'I', 'Q, 'mod()=mod()+mod()'}, '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{'sub': I', 'Q, 'claim-text': {'br': None, 'i': A,B', 'A+B/', 'B]−B/, 'mod()=[(2)% 2'}, 'where xis a real component of a complex input signal, x, is an imaginary component of the complex input signal, and mod(·) is a modulo function and is defined as followswhere 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 ...
