ANALOG-TO-DIGITAL CONVERSION WITH NOISE INJECTION VIA WAVEFRONT MULTIPLEXING TECHNIQUES

摘要

A novel noise injection technique is presented to improve dynamic range with low resolution and low speed analog to digital converters. This technique combines incoming signal and noise signal with wave front de-multiplexer and split into several channels. Then low resolution and low speed analog to digital converters are used to sample each channels. All signals are recovered using wave front multiplexer. For advanced design, ground diagnostic signals with optimizing processor can be added to guarantee recovery quality.

1. An apparatus for processing signals, comprising:
a first processor configured to receive a first signal and a second signal and generate a third signal containing information from said first and second signals; a second processor configured to apply a vector to recover information associated with said third signal into a first output associated with said first signal and a second output associated with said second signal; and an optimizer configured to adjust said vector.
