In this paper sound steganographic system receiver structure with signal spectrum broadening is proposed and researched. This receiver consists of rehabilitate filter with adaptive coefficients and correlation receiver. Steganographic system algorithms with blind coder and decoder procedure are researched. It is shown that the rehabilitate filter with adaptive coefficients application provides essential increase in probability of correct binary detection of off-stage information or allows adding 30 times more bits of built-in data.
