FIELD: radio engineering, communication.
SUBSTANCE: logical diagram of physical layer under control of program code, written on the computer readable recording medium, generates data stream of the physical layer presentation protocol data unit (PPDU) formed for the one megahertz bandwidth; interleaving the bit of data stream in which the bits are located in a table having eight columns and 3*NBPSCS rows, where NBPSCS denotes the number of coded bits per subcarrier; generating the communication signal by orthogonal frequency division multiplexing (OFDM), including a plurality of subcarriers, in which a plurality of subcarriers includes twenty-four data subcarriers, two pilot subcarriers, five guard subcarriers, and one direct current (DC) subcarrier.
EFFECT: increasing the transmit channel capacity.
