摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus of detecting a response end point of a radio frequency identification tag which can detect an end of signal (EOS) of a received response signal in order to transmit a subsequent signal within a predetermined time, when receiving the response signal from an RFID tag after transmitting a command signal from a reader of a radio frequency identification system to the RFID tag.
SOLUTION: The method of detecting the end of signal for the radio frequency identification tag includes a step of obtaining a threshold based on a continuous signal in a section having no response signal; a step of measuring a variance value in a sliding window while moving the sliding window for the response signal; a step of comparing the variance value with the threshold and counting the number of times when the variance value is smaller than the threshold; and a step of determining that a time when the number of counts is not less than the predetermined times is the end of the response signal.

摘要： A method for managing a network in which Bluetooth equipped devices (300) are linked together when the network master (400) cannot serve as a master. During normal operation, the network master (400) updates the backup master rank information when the network master (400) disappears, in a predertimined cycle, according to link information, such as received signal strength indication (RSSI) or link quality, transmitted from the Bluetooth equipped devices serving as a slave. When power of the network master (400) is exhausted, or when the network master (400) leaves the network operating region, a new master is selected from the remaining slaves according to the backup master rank information, thereby reconfiguring a network around the new network master. The method enables proper designation of a new master when a preexisting network master (400) leaves the network operating region, thereby increasing a probability of holding connection throughout the network.

摘要： A method for controlling errors in a wireless link layer using a simultaneous multiple copy scheme and an adaptive forward error correction (FEC) scheme in a wideband wireless communication is provided. The method for controlling errors in a link layer in wideband wireless communication using an automatic repeat request (ARQ) scheme, in which a wideband wireless channel is used for communication between a first node and a second node, includes the steps of (a) estimating the error ratio of a forward (a direction in which a cell is transmitted from the first node to the second node) channel using the state of a backward (a direction in which a cell is transmitted from the second node to the first node) channel, and transmitting a cell, in which a forward error correction (FEC) code having an encoding ratio that varies depending on the estimated error ratio is included in a protocol data unit (PDU) of a wireless link layer, through the forward channel and (b) re-transmitting the copy of a cell transmitted in the step (a), when feedback information that indicates that an error exists in the cell transmitted in the step (a) is received through the backward channel. It is possible to reduce the number of times of re-transmission by improving the probability of correcting forward errors using more error controlling bits as the state of the channel is worse and to minimize the waste of resources using less error controlling bits as the state of the channel is better, to thus obtain the optimal performance and guarantee the minimum delay time.

摘要： The invention provides a method for controlling errors using a hybrid ARQ scheme employing a simultaneous multiple copy mode (i.e. transmitting several copies of a cell in a single frame when re-transmission is requested) and adaptive forward error correction (FEC) in a wideband wireless ATM communication system. The error ratio of a forward channel is estimated using the state of a reverse channel and, on the basis of this estimation, an encoding ratio for the forward error correction is selected. FEC encoded data is then mapped or converged onto fixed length protocol data units (PDUs) of the wireless link layer for transmission, with the mapping/convergence adapting to changes in the selected FEC encoding ratio (see figures 5 and 6). Using stronger FEC for poorer channels reduces the number of re-transmissions required, whereas a lower level of FEC for good channels maximises the available bandwidth.
