摘要：
PURPOSE: A symbol combination based Alamouti transmission method for collaborative communication in a fading channel is provided to obtain a cooperative diversity gain through asynchronous collaborative communication. CONSTITUTION: A source node inserts a CP(Cyclic Prefix) for interference cancellation between symbols(403). The source node transmits transmission blocks to two relaying nodes. Each relaying node performs complex multiplication in received symbols(404). Two relaying nodes transmit symbols in which the complex multiplication is performed to a destination node(405). The destination node obtains an alamouti code structure by removing cyclic prefix from the received symbols(406). The destination node decodes data(407). [Reference numerals] (401) Generating two data blocks in a source node; (402) Generating two transmission blocks by combining two data blocks in a source node; (403) Inserting cyclic prefix for interference cancellation between symbols into two data blocks and transmitting the two data blocks to a source node; (404) Executing complex number multiplication for symbols individually received in two relay nodes; (405) Transmitting symbols in which complex number multiplication is executed to each destination node by two relay nodes; (406) Obtaining an alamouti code structure by removing cyclic prefix from symbols received in a destination node; (407) Decoding data in a destination node by using a symbol unit maximum likelihood high speed decoding method
