Abstract  Abstract

Systems methods and DEVICES FOR coding OF SPEECH IN BROADBAND. One encodificador of the broadband speech of according with one embodiment includes one encodificador narrow band and one of encodificador a high bandwidth. The encodificador of narrow band is configured for encodificar a portion of narrow band of one signal of the broadband talk groups in a set of filter parameters and corresponding one of excitation signal encodificado. The encodificador a high bandwidth is configured for encodificar according with one of the excitation signal of high bandwidth a portion of the high-band signal of the broadband for talk groups a set of filter parameters. The encodificador a high bandwidth is configured for generate the signal excitation of a high bandwidth by application of a non-linear function to one signal based in the excitation signal of narrow band encodificado for generate one spectrally extended signal.
