Abstract: Techniques pertaining to transmission methods of probabilistic shaping (PS) modulation in wireless communications are described. An apparatus (e.g., station (STA)) processes each subblock of a plurality of subblocks of a data unit by padding each subblock after scrambling and PS mapping each subblock to result in each subblock having a fixed length before further processing including encoding and modulation. The apparatus then transmits the plurality of processed subblocks.

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.
