Abstract: A device and a method, for detecting signals, which effectively analyze and trace abnormal signals which are unintended or different from normal signals are provided. The provided device for detecting signals includes: a signal reception unit to receive signals from the outside; an analog/digital signal processing unit to determine whether a signal is an abnormal signal or not for the signals received in the signal reception unit based on a plurality of signal profiles which have different signal characteristics and obtaining the abnormal signals when the received signals are abnormal; and a user interface unit for displaying the abnormal signals through the analog/digital signal processing unit. The method of the present invention is more accurate than matching through an existing simple frequency/bandwidth search by detecting abnormal signals based on profiles which are designated by a user and is capable of distinguishing a type of transmitter.

Abstract: PURPOSE: A low-delay formant FEC(Forward Error Correction) method is provided to use formant components of a future frame as surplus information used for restoring voice packet loss, thereby reducing delay and improving sound quality. CONSTITUTION: An input voice frame is compressed after a frame delay and a look-ahead delay, and a voice packet is generated after a compressive processing delay(310). A formant preparing for loss of the input voice frame is extracted(312). Packets are transmitted after the compressive delay(314). When the packets are transmitted from a transmission terminal, the packets arrive at a receiving terminal after a transmission delay(316). A certain packet is lost among the receiving packets inputted to a CODEC of the receiving terminal(318). When the packet is lost, the lost packet is restored by using surplus information(320).
