Compressed sensing in speech signals
open-in-new
<p>In <a href="/facts/Communications_technology/wG6q8RfN">communications technology</a>, the technique of <a href="/facts/Compressed_sensing/aR5DQm3n">compressed sensing</a> (CS) may be applied to <a href="/facts/Speech_processing/jUjXoYwc">the processing of speech signals</a> under certain conditions. In particular, CS can be used to reconstruct a <a href="/facts/Sparse_vector/FFtN0XjR">sparse vector</a> from a smaller number of measurements, provided the signal can be represented in sparse <a href="/facts/Domain_(mathematical_analysis)/xT44oI3E">domain</a>. "Sparse domain" refers to a domain in which only a few measurements have non-zero values. </p>
