Title:
TRANSMITTER, RECEIVER, AND SEMICONDUCTOR CHIP
Document Type and Number:
Japanese Patent JP2016149740
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve a BER characteristic in a MIMO system.SOLUTION: A transmitter 1 performs mapping of data distributed for each transmission antenna on an IQ plane to generate a carrier symbol; decomposes a plurality of carrier symbols into I data and Q data before performing interleave processing in the time direction on inter-polarization interleave data obtained by rearranging either of the I data and Q data according to a predetermined rule; and generates an OFDM signal. A receiver 2 performs MIMO separation on time deinterleave data obtained by performing deinterleave processing in the time direction on a complex baseband signal of the OFDM signal; and rearranges either of odd-numbered data and even-numbered data of a plurality of pieces of MIMO-separated data according to a predetermined rule before taking data adjacent to each other as I data and Q data to generate a carrier symbol.SELECTED DRAWING: Figure 1
