An interrogating and processing system and method is described. The pulse detonation system includes a pulse detonation core assembly comprising at least one detonation chamber configured to detonate a fuel mixture. The strategy is sufficient to result in a product copolycarbonate with improved color. The method is suitable for use with a variety of data mining techniques including support vector machines, neural networks and decision trees. Up-converters up-convert the phase compensated prefixed OFDM symbols to respective radio frequency bands having center frequencies and bandwidths that preserve the OFDM multi-carrier structure.
