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.

Claim (Index 10):
An analog front end (AFE) for use in a system including a radio frequency digital baseband transmitter interfaced at a transmit end to a communications link, the transmitter to generate a radio frequency compressed baseband digital data signal, the AFE comprising:\n a receive interface including an input com port to interface at a receive end to the communications link; the receive interface configured to receive through the input com port the compressed baseband digital data signal communicated over the communications link; the compressed baseband digital data signal generated from a radio frequency baseband discrete data signal that includes a TX inband signal component, and a DPD signal component based on digital pre-distortion of the TX inband signal component,\n the TX inband signal component quantized with a pre-defined first bit precision to provide a TX quantized data signal, and \n the DPD signal component quantized with a pre-defined second bit precision to provide the DPD quantized data signal, \n the second bit precision less than the first bit precision, and \n the compressed baseband digital data signal generated with the TX and DPD quantized data signals; \n decompression logic including\n bit unpacking logic to separate the compressed baseband digital data signal into the TX and DPD quantized data signals; \n combining filter logic to filter the TX and DPD quantized data signals into TX and DPD filtered data signals, combined into a decompressed baseband digital data signal corresponding to the radio frequency baseband digital data signal including the TX and DPD signal components; and \n radio frequency conversion circuitry to convert the decompressed baseband digital data signal to an analog radio frequency signal corresponding to the radio frequency baseband discrete data signal including the TX inband and DPD signal components.
