Title:
TRANSMISSION DEVICE, RECEPTION DEVICE, AND SEMICONDUCTOR CHIP
Document Type and Number:
WIPO Patent Application WO/2016/129272
Kind Code:
A1
Abstract:
The purpose of the present invention is to improve BER characteristics in a MIMO system. A transmission device 1: generates a carrier symbol by mapping data, which is distributed to each transmission antenna, onto an IQ plane; interleaves, in the time direction, polarized wave-interleaved data obtained by interleaving a plurality of carrier symbols among a plurality of transmission antennas; and generates an OFDM signal. A reception device 2: MIMO-separates time-deinterleaved data obtained by deinterleaving, in the time direction, a complex baseband signal of an OFDM signal; and generates a carrier signal by deinterleaving a plurality of MIMO-separated data among a plurality of reception antennas.
