Abstract: 상기최적협동중계방법및 시스템에따르면, 다중홉 협동통신시스템에서채널의특성에따라제1 중계방법과제2 중계방법을선택적으로이용함에따라채널의상태변화에영향을받지않으며신뢰성있는성능을갖는최적의협동통신방식을제공할수 있다. 또한, 수신된신호에대하여순환중복검사를통해그 정확도를판단하고, 각각의홉마다에러가발생한중계기의개수와임계값을서로비교함으로써채널의특성을간단하게파악할수 있는이점이있다. 더욱이, 상기임계값을적절히조절하는경우시스템전체의파워를조절할수 있다.

Abstract: PURPOSE: A method for improving the throughput of cooperative communication using hierarchical modulation and a system thereof are provided to maintain a stable bit error rate. CONSTITUTION: A data classified into a plurality of layers receives modulated signal per layers from a transmitter. A repeater(120) demodulates the received signal. The repeater performs CRC(Cyclic Redundancy Check). The repeater modulates the received terminal coping with the CRC result. The repeater transmits the modulated received signal to the receiver.

Abstract: PURPOSE: An optimal cooperating relay using cyclic delay diversity in multi-hop networks is provided to differently apply relaying method by the property of channels. CONSTITUTION: A determining unit(121) performs a CRC(Cyclic Redundancy Check). The determining unit decides the accuracy of the received signal. An estimating unit(122) sums the number of repeaters in which an error is generated at a hop based on the determined result of the determining unit. The estimating unit estimates a property of the previous channel. If the sum of error generated repeaters is larger than a predetermined threshold value, a transmit unit(123) transmits the received signal through a first relaying method.
