Abstract

Official abstract text for this publication.

Transmission quality is improved in an environment in which direct waves dominate in a transmission method for transmitting a plurality of modulated signals from a plurality of antennas at the same time. All data symbols used in data transmission of a modulated signal are precoded by hopping between precoding matrices so that the precoding matrix used to precode each data symbol and the precoding matrices used to precode data symbols that are adjacent to the data symbol in the frequency domain and the time domain all differ. A modulated signal with such data symbols arranged therein is transmitted.

First claim

Opening claim text (preview).

The invention claimed is: 1. A transmission method comprising: generating a first modulation signal s1 by using a first modulation scheme; generating a second modulation signal s2 by using a second modulation scheme; regularly switching between a plurality of precoding matrices for generating a first precoded signal z1 and a second precoded signal z2; generating the first precoded signal z1 and the second precoded signal z2 by applying one of the plurality of precoding matri…
