Patent ID: 10505582

Abstract:
Signal compression for serialized data bandwidth reduction based on decomposition of a data signal into separate signal components with different SQNR or dynamic range requirements, and quantizing the signal components with different bit precisions. Compression logic decomposes the input data signal into the first/second signal components, quantizes the first component with a pre-defined first bit precision to provide a first quantized data signal, quantizes the second component with a pre-defined second bit precision to provide a second quantized data signal, the second bit precision less than the first bit precision, the first and second quantized data signals bit packed into a compressed digital data signal. At the receive-end, decompression logic bit unpacks the compressed digital data signal into the first/second quantized data signals, and filters/combines the first/second quantized data signals into a decompressed data signal corresponding to the input data signal including the first and second signal components.
