摘要： In a DSTBC system, to obtain a communication system capable of estimating a transmission path without reducing a transmission capacity. The communication system includes a transmission device and a reception device that perform communication in the DSTBC system, in which the transmission device performs, as a start symbol of DSTBC, the start symbol including known signals one of which has signal power and the other of which are set to signal power of zero and transmits the known signals to the reception device, and the reception device independently estimates a transmission path between each of transmitting antennas of the transmission device and a receiving antenna of the reception device itself by using the space-time coded start symbol received from the transmission device, and decodes a reception signal with DSTBC decoding employing synchronous detection.
