Patent ID: 8811503

Claim:
An apparatus configured to generate a space frequency block code (SFBC) relay signal, the apparatus comprising: a signal detection unit configured to detect a received signal by receiving first and second source signals transmitted from first and second source nodes in a first time slot; a relay signal generation unit configured to generate a relay signal to be equal to a sum of a result of a conjugation operation on the received signal in a time domain, and a result of a time shift operation and a convolution operation on the received signal in the time domain, the relay signal cooperating with the first and second source signals and being encoded using a SFBC scheme; and a signal transmitter configured to transmit the relay signal to a destination node in a second time slot, wherein the first and second source nodes are mobile terminals and the destination node is a base station, and wherein the destination node receives the relay signal from the signal transmitter, the first source signal from the first source node, and the second source signal from the second source node in the second time slot.
