Abstract :
How to reduce Peak to Average Power Ratio (PAPR) of multi-carrier jam signal was analyzed. A method to reduce PAPR of multi-carrier signal with improved Genetic Algorithm (GA) is proposed with non-linear coding. Fitness function and coding rule was proposed. Peak of multi-carrier signal was optimized by seek combination of carrier phase. The multi-carrier signals which have 16 or 32 carriers were effectively optimized by this method respectively.
