Multipath Cancellation Using a Maximum Likelihood Metric Space
Abstract
Multipath signals occur in many sonar, radar, and communication applications. It is, of course, generally desirable to eliminate these unwanted signals. Traditional array signal processing techniques often have trouble eliminating these signals when only a small number of array elements are available. The maximum likelihood method explicitly models multiple signals in its mathematical construction. This feature effectively opens up a multidimensional space that allows the desired direct path signal to be completely from the multipath signals. Examples with both narrowband and broadband signals are presented.
