Abstract: 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.

Abstract: Channel data for a plurality of OFDM tones for one or more spatial or space-time streams are determined. A plurality of angle values associated with the one or more spatial or space-time streams and the one or more OFDM tones of the plurality of OFDM tones are determined. For each of the one or more spatial or space time streams, a per-tone signal to noise ratio (PT-SNR) associated with one or more OFDM tone of the plurality of OFDM tones is determined, and an average signal to noise ratio (avg-SNR) is determined by averaging signal to noise ratio (SNR) values corresponding to one or more OFDM tones of the plurality of OFDM tones. A feedback report is generated to include at least i) the plurality of angle values, ii) the PT-SNRs, and iii) the avg-SNR.
