Patent ID: 8897208

Claim:
A space frequency block code signal relaying system, the relaying system comprising: a relay station comprising a receiver configured to receive, via a radio channel, a first source signal sent from a source station and detect the received signal in a first time period; a relay signal processor configured to generate, in the first time period, a relay signal corresponding with a second source signal transmitted from the source station to a destination node based on the received first source signal, the first source signal and the relay signal being signals encoded in a Space Frequency Block Code (SFBC) scheme; and a signal transmitter configured to transmit the relay signal to the destination node in a second time period, wherein the second source signal transmitted from the source station to the destination station is transmitted directly from the source station to the destination node in the second time period without using the relaying system, wherein the relay signal is generated in the first time period equal to a sum of a result of a conjugate value and a result of a time shift operation and a convolution operation on the received first source signal of a time domain, and wherein the destination node does not detect the first source signal in the first time period.
