Tdoa localization with mbed

[farisabdat]

i am currently doing a project similar to this using mbed system with two electret microphone breakboard from sparkfun. I am amazed by the sum of the algorithm that you have derived. i respect your work and effort that you have made.But i do have certain question to ask regarding this project that u have completed.i am not familiar with matlab programming and i have not touch on it before during my study.Do u have a c++ format of the program? so that i could further understand on it. In your expository paper, you stated that it only yields a solution when M>=5. To my next question, do my 2 microphone work similar when using with your algorithm?

Do u have a c++ format of the program?

Sorry, I don't. If you know c++ and can find c++ libraries for cross-correlation http://en.wikipedia.org/wiki/Cross-correlation and Moore-Penrose pseudoinvers http://en.wikipedia.org/wiki/Moore%E2%80%93Penrose_pseudoinverse and start with a basic scaffold of the program, I can help fill in the mathematical details.

do my 2 microphone work similar when using with your algorithm?

This algorithm won't work with 2 microphones. To locate the source of the acoustic signal in 3d, this algorithm needs 5 microphones.

ok sure.i'll work on that and give u an update.thanks for ur help.is it possible if i show u once i'm done?
