Hybrid forwarding apparatus and method for a cooperative relay network in an orthogonal frequency division multiplexing method

摘要

The present invention for the hybrid forwarding apparatus and method for a cooperative relaying in an orthogonal frequency division multiplexing scheme network, a repeater for transmitting data using a repeater in an orthogonal frequency division multiplexing scheme network hybrid forwarding (Hybrid Forwarding) to the device in the transmission forwarding scheme decision to for forwarding structure selector and, AF (amplify and forward) method is used, the forwarding structure selector from service data received the amplified AF portion and, DF (Decode and forward) method is used, the forwarding structure selector from providing received data for decryption, and coding for DF portion, and the AF unit and DF negative output data to OFDM (Orthogonal Frequency Division Multiplexing) modulator to provide a for a multiplexer (multiplexer) for including to that repeater has communication links on the SNR for obtain the bit error probability based on the determined transmission scheme. Thus, the bit error probabilities, so by selecting the more appropriate method to use based on the forwarding, there is the advantage of obtaining a higher rate communication link that has a lower bit error probability. ; Repeater (Relay), hybrid forwarding (Forwarding Hybrid), OFDM (Orthogonal Frequency Division Multiplexing).
