Add to ORKGMixed transform coders have been shown to consistently yield higher signal quality than those based on one transform for a fixed compression ratio. However, these coders have not been widely employed due to the very high computational complexity of existing formulations. This paper presents a new recursive parallel mixed transform technique employing a novel projection algorithm for signal representation. Formulations are derived, algorithms are described and results of simulations are presented. Excellent performance is achieved with much less computation than required by existing mixed transform techniques, making real-time implementations possible
