Novel Karaoke and Multi-Channel Data Recording / Transmission Techniques via Wavefront Multiplexing and Demultiplexing
A concurrent multi-channel data process is presented to utilize wavefront multiplexing for data storage and data stream transport in a distribution network, with additional applications for multi-media recording and data communications via transponding satellites. Multiple concurrent data streams are pre-processed by a wavefront multiplexer into multiple sub-channels or wavefront components, where signals from respective data streams are replicated into sub-channels. These replicated data streams are linked via a unique phase weighting vector, or “wave-front”, which are also linked by various spatially orthogonal wavefronts. Additionally, probing signals are embedded and linked via some of the orthogonal wavefronts. Aggregated signals in sub-channels are unique linear combinations of all input data streams. Post-processing via a wavefront de-multiplexer converts various sub-channel signals back to the original data streams, utilizing the embedded probing signals to restore orthogonality among multiple wavefronts.
