Adaptive Speech Compression and Decompression for Communications

High digital compression ratios are spectrally efficient; however, excellent fidelity makes the application in radio very useful. LPC (Linear predictive coding) methods have been honed for mobile communication; but a more generic form of compression, which can be applied to ham radio and personal communication services (PCS) in the private sector would extend the usefulness of these applications and services. Using AI and self-training techniques, a high fidelity coding a decoding library can be developed by the layman on a computer and applied to radio voice applications using properly equipped hardware. This paper discusses the coding and decoding algorithm, as well as the recommended hardware and software for implementation.
