ULTRA-WIDEBAND SIGNAL DETECTION AND PULSE MODULATION

摘要

Ultra-Wideband communication signals are analyzed based on an overcomplete dictionary that includes sub-dictionaries associated with noise (such as additive white Gaussian noise), interference, impulses, or signal pulse positions. The communication signal is represented with one or more combinations of words of the overcomplete dictionary, and a preferred representation is selected. Based on the preferred representation, an estimate of transmitted data is obtained. With sub-dictionaries based on signal pulse positions, the data estimate is based on a word associated with a signal pulse position.
