title = "Tiled time delay estimation in mobile cloud computing environments",
abstract = "We present a tiled delay estimation technique in the context of Mobile Cloud Computing (MCC) environments. We examine its accuracy in the presence of multiple sources for (1) sub-sample delays and also (2) in the presence of phase-wrap around. Phase wrap-around is prevalent in MCC because the separation of acoustic sources may be large. We show that tiling a histogram of instantaneous phase estimates can improve delay estimates when phase-wrap around is significantly present and also when multiple sources are present. We report that error in the delay estimator is generally less than 5\% of a sample, when the true delay is up to 10 samples for three source mixtures.",
