A biosignal transmitter comprising: a biosignal obtaining unit configured to obtain a biosignal comprising a plurality of unit signals; a parsing unit configured to parse the biosignal to extract a first unit signal of the plurality of unit signals; a pattern obtaining unit configured to obtain a pattern (315, 325) related to the biosignal based on the first unit signal; and a transmitting unit configured to transmit information related to a feature point of the first unit signal based on the first unit signal and the pattern, wherein the pattern obtaining unit comprises: a determining unit configured to determine whether a pattern corresponding to the waveform of the first unit signal is already generated; an obtaining unit configured to obtain the pattern in response to a determination that the pattern is generated; and a generating unit configured to generate the pattern (325; 415) in response to the determining unit determining that the pattern is yet to be generated, by receiving, from the parsing unit, a predetermined number of unit signals, and calculating an average of the received unit signals, wherein the transmitting unit is further configured to: calculate a correlation between the first unit signal and the pattern; extract the feature point and transmit a first type signal comprising only the information related to the feature point in response to the correlation being greater than or equal to a predetermined threshold value, or transmit a third type signal comprising the first unit signal in response to the correlation being lower than the predetermined threshold value; and transmit further a second type signal comprising the pattern in response to the pattern being newly generated by the pattern obtaining unit. a biosignal obtaining unit configured to obtain a biosignal comprising a plurality of unit signals;
