Abstract
Disclosed are a long-range radio communication method and device based on a spreading factor index, the method including: within one symbol period, dividing a plurality of information bits into index bits and modulated bits; mapping the index bits into a spreading factor sequence, and generating first chirp signals corresponding to various spreading factors (SFs); and converting the modulated bits to decimal numbers associated with the various SFs, modulating the decimal numbers into carrying signals, multiplying the carrying signals by the first chirp signals associated with the SFs to obtain second chirp signals associated with the various SFs, and superposing the second chirp signals to obtain a transmitted signal. According to the disclosure, by combining different SFs, an additional dimension is created to carry more information bits, so as to achieve the effect of increasing a data rate.
