Abstract
A transmitter device arranged to encode a set of digital input data into a succession of modulated chirps, whereby said digital input data are encoded according to a Gray code into codewords () having a plurality of bits, and having an interleaver that distributes the bits (C, . . . C) of each codeword into a series of digital modulation values (S, . . . S), at different bit positions, and to synthesize a series of modulated chirps whose cyclical shifts are determined by the modulation values. A special frame structure is defined in order to ensure high robustness, and variable bit-rate flexibility.
