Title:
COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/117200
Kind Code:
A1
Abstract:
Provided is technology that can ensure communication quality even without the provision of additional functionality such as phase correction. When operating as a transmission-side device, a base station device and a communication terminal device generate a transmission signal such that there is no phase rotation at the front of a demodulation reception window set at a receiving-side device, by causing Inverse Fast Fourier Transform (IFFT) output to be rotated, and copying the last portion of the post-rotation IFFT output to the front of the post-rotation IFFT output as a Cyclic Prefix (CP).
