There is provided an incoherent UWB-IR communication method by which erroneous demodulation is difficult to occur even in a multipath environment. Thus, the present invention includes an incoherent wireless communication method including a first step of modulating transmission data, a second step of converting the modulated transmission data into pulses and converting the pulses received from the external into reception data, and a third step of demodulating the reception data, wherein the pulses used in the second step includes a plurality of pulse sequences and the plurality of pulse sequences is such that the peaks of cross-correlation values are lower than the peaks of autocorrelation values.
