摘要

The invention relates to a signal encoder (110) for generating N' parallel binary signals (C₀, C₁, C₂, C₃, C₄) based on B information bits (b₀, b₁, b₂,b₃). Said encoder comprises a vector mapping device for the non-linear mapping of possible bit patterns of the B information bits to 2^B signal combinations on the N' parallel binary signals, where N' is greater than B. The signal encoder for generating a plurality of individual modulation symbols based on B information bits comprises a vector mapping device for the non-linear mapping of possible bit patterns of the B information bits to various 2^B combinations consisting of at least two individual modulation symbols, the various 2^B combinations representing a real subset of a complete modulation alphabet. Said complete modulation alphabet is formed by a cross product of sets of actual occurring modulation values of the two individual modulation symbols. The concept according to the invention permits the digital transfer of information using a redundant space code, allowing information to be reliably transferred even if a rough quantization exists.
