In this paper, we have proposed a Cognitive Radio system where primary users uses the precautionary measures against the possible interferences that may disturb their quality of service (QOS), these interferences may be originated from any other primary user itself, possibly due to the effect of the hidden terminal problem or may be received from the(More)
The calculation of time delay between a signal and its echo received at a microphone has been proven to be a useful parameter. Speech enhancement, speaker localization, speech and speaker recognition are few applications of TDE methods. We are implementing various methods for the estimation of time delay. These methods are implemented in MATLAB. The reason(More)
