    摘要： Provided is a carrier frequency recovering apparatus and method based on phase shift. The carrier frequency recovering apparatus can recover carrier frequency based on phase shift caused by a frequency offset to thereby perform demodulation without deterioration, no matter how large the frequency offset is, and minimize structural complexity, although a frequency offset tolerance range is higher than a symbol rate and a method thereof. The carrier frequency recovering apparatus includes a phase shift estimation part for estimating a phase shift value caused by a frequency offset based on a received preamble signal; a compensation part for compensating a receiving signal based on the estimated phase shift value obtained in the phase shift estimation part prior to differential decoding; and a detection part for detecting the compensated signal obtained in the compensation part.

    摘要： Provided is a method for switching a piconet device to a coordinator in a piconet. The method receives the latest order of precedence as the next PNC information from the current PNC. Thereafter, the method detects a P-CTA allocated to devices of the piconet using a beacon of a superframe received from the PNC. On failing to receive a beacon from the PNC, the method detects whether “beacon non-receipt” indicating information that is transmitted between piconet devices during the detected P-CTA. If the “beacon non-receipt” indicating information is not detected, the method does not perform a PNC appropriation operation. If the “beacon non-receipt” indicating information is detected, the method determines that the PNC has left the piconet without performing a normal PNC handover procedure and thus performs a PNC appropriation operation according to the order of precedence information.

    摘要： Disclosed is a binary signal modulator for minimizing deterioration of receiving performance caused by phase error. The binary signal modulator receives binary signals, and converts the binary signals into complex symbols according to a predetermined mapping relation. Here, the mapping relation is generated when a plurality of mapping symbols are arranged on a plurality of trajectories so that the distance between the mapping symbols is greater than or equal to a predetermined distance and the phase between the mapping symbols is greater than or equal to a predetermined angle from among the trajectories starting from a plurality of points on the complex plane, and a distance between the trajectories is greater than or equal to the minimum distance from among the distances between the points.

    摘要： Disclosed is an uplink random access procedure in an NB-TDD (Narrow Band Time Division Duplexing) system. To achieve an acknowledgement for data transmission from a UTRAN (UMTS Terrestrial Radio Access Network), a UE selects one of a plurality of sync codes by which the UTRAN identifies UEs that request data transmission and transmits the selected sync code in a time slot of a sub-frame to the UTRAN. Then, the UE receives the sync code information, information about the arrival time of the sync code, time update information indicating a variation in the transmission time of data, and power information indicating an adjustment to a power gain in the UE from the UTRAN on an FPACH (Fast Physical Access Channel). The UE transmits the data on a P-RACH (Physical Random Access Channel) mapped from the FPACH according to the time update information and the power information.
