Title:
COMMUNICATION SYSTEM, TRANSMISSION DEVICE, RECEPTION DEVICE, COMMUNICATION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2014/174754
Kind Code:
A1
Abstract:
Provided is a band-limited communication system including a transmission device and a reception device, wherein the transmission device is provided with a prefix addition unit for adding, to the head of each of blocks of transmission data, a prefix to which data of a predetermined length at the tail end of each of the blocks is copied, and a transmission unit for transmitting each symbol of the transmission data to which the prefix is added at time intervals shorter than a Nyquist rate corresponding to the band of the communication system, and the reception device is provided with a prefix removal unit for removing the prefix from each of blocks of reception data, and an interference removal unit for removing inter-symbol interference caused by the transmission unit transmitting the symbol at time intervals shorter than the Nyquist rate in each of the blocks from which the prefix has been removed.
