Jun-Hyun Park,Dong-Kyu Kim +1 more
TL;DR: In this article, a multi-carrier transmission system which includes an encoder for converting a data sequence into encoded symbols corresponding to respective sub-carriers, a first shifter for rearranging the encoded symbols to define a guard interval length, an inverse fast Fourier transform (IFFT) unit for inverse fast-fourier transforming the rearranged encoded symbols, a second shifter processing the transformed symbols to effect a frequency shift to compensate for a frequency shifting effected by the IFFT unit, and an interleaving symbol replicas with the processed symbols according to
Patent
OFDM receiving device and method for beam forming with uneven beam width based on channel properties
TL;DR: In this paper, the beam formation azimuth of an OFDM receiving device was adjusted by calculating the beam coefficient from the detected signal during decoding of a receiving signal, thereby improving the receiving signal accuracy.

TL;DR: In this paper, an OFDM communication device having a plurality of individually-aligned antennas includes a receiving signal generating unit for decoding and restoring OFDM signals from the plurality of antennas, a beam coefficient calculating unit for calculating channel property information inclusive of a signal to noise rate, from the signal received from the receiving signal generator, and calculating the beam coefficient of an antenna.
Patent
Multi-carrier transmitting system and its data transmitting method
TL;DR: In this paper, the authors proposed a multi-carrier transmission system which includes an encoder for converting data to be transmitted into a subcarrier, a first shifter for shifting a phase of each subcrier in one frame provided from the encoder, an inverse fast Fourier transform (IFFT) unit for transforming from the sub-carriers subjected to the phase shift in a frequency domain into a digital data string in a time domain, and an inserter for copying part of the rearranged data string, rearranged by the second shifter to add it
