FIELD: information technology.
SUBSTANCE: apparatus for transmitting data comprises an encoder for encoding data, a multiplexer for multiplexing the encoded data and a training sequence code (TSC), a modulator for modulating the multiplexed data using a defined modulation scheme and a transmitter for transmitting the modulated data. The modulator modulates TSC based on two constellation points having the highest absolute value and opposite signs among M constellation points in the constellation according to the defined modulation scheme.
EFFECT: high efficiency of transmitting and receiving data using a training sequence code.
