Wideband DOA estimation

Started by sherrykhan78 March 6, 2006
Hi,
I am working on DOA estimation using super resolution methods for wideband
signals, I am in need matlab code for wideband MUSIC and ESPRIT coherrent
and incoherrent. 
Your help regarding these will benifit me a lot.
Thanks in advance
Khan

First, the mentioned methods are based on the narrow-band signal model. It is not obvious how to extend such methods to the wideband situation. If your work (some thesis?) is based on such a method being available, you would have to implement it yourself. This is, at best, a highly speculative R&D area, so you don't want to depend on other people's work here. I don't have the faintest clue how the term "incoherent" is in any way relevant to the MUSIC and ESPRIT methods. The basis of these methods is that the incoming signal is coherent across the reciever array. If the signal for some reason is incoherent, these methods break down. Rune
