说明：  Estimating the positions of sensor nodes is a fundamental and crucial problem in ad hoc wireless sensor networks (WSNs). In this paper, an accurate node localization method for WSNs is devised based on the weighted least squares technique with the use of time-of-arrival measurements. Computer simulations are included to evaluate the performance of the proposed approach by comparing with the classical multidimensional scaling method and Cram´ er-Rao lower bound.

audio codec, includes LPC,The code was tested on male and female speech files recorded using a microphone on my pc and also tested on the wavefiles of the TIMIT database. The results are found to be good enough. I have attatched 5 sample wavefiles, on which I have tested my code.
