Summary: 
AOC-SS (Advanced Orthogonal Code Spread Spectrum) modulation [1] is a flexible scheme that offers multi-rate transmission but causes a PAPR (Peak-to-Average Power Ratio) increase in proportion to the number of AOCs. Our solution to this problem is a new mapping technique. In addition, by combining with STC (Space-Time Coding), AOC-SS can resist multi-path fading. Computer simulations validate the proposed scheme.
