摘要：ＲＦタグの場所および方位の決定は、拡張型無線周波数三角測量を通して遂行される。ビーコン配列は、特別に設計されたビーコンノードからＲＦタグの方向を決定する。ＲＦタグの場所特定は、複数の空間的に位置がずれたビーコンノードからこの測定を行うことによって達成される。ビーコンノードは、複数のアンテナを具備、異なるアンテナに循環的に切り替えられる各シンボルを伴うフレームを伝送する。異なる距離を進行するシンボルは、ＲＦタグによって受信されたフレーム内に位相偏移をもたらす。位相偏移およびアンテナの既知の配列から、ＲＦタグが特定のビーコンノードからＲＦ可視性である角度が、推定され得る。

摘要： PURPOSE:To obtain correct zone lane display at all times in a decometer of a receiver, by generating carry up or carry down pulses by sensing the lane slip when it occurs. CONSTITUTION:A decometer signal from the receiver is applied to the decometer 11, and the % lane value is displayed. The contents of the decometer 11 is digitized through an A/D converter 11A, sampled in a sampling circuit 16 together with the contents of a zone lane counter 14, and written in a data memory circuit 17. The data written in the data memory circuit 17 is processed in a folding circuit 18, written in a memory circuit 19, averaged in an averaging circuit 20, and inputted into a data difference judging circuit 21. The data difference judging circuit 21 senses the lane slip in the decometer 11, generates the carry up or down pulses, and compensates the lane value in the zone lane counter 14.

摘要： A wireless terminal receives signaling information, pertaining to a reference signal transmission in at least one specifically designated sub frame, the signaling information including a list, the list including base station identities. The terminal determines, from at least one of the base station identities in the list, the time-frequency resources associated with a reference signal transmission intended for observed time difference of arrival (OTDOA) measurements from a transmitting base station associated with said one base station identity. The time of arrival of a transmission from the transmitting base station, relative to reference timing, is measured. The wireless terminal can receive a command from a serving cell to start performing inter-frequency OTDOA measurement on a frequency layer containing reference signals, the frequency layer distinct from the serving frequency layer, the serving frequency layer not containing positioning reference signals. The wireless terminal can perform OTDOA measurements subsequent to the reception of the command on a carrier frequency different from the serving cell carrier frequency. A base station transmitter can jointly schedule a reference signal transmission from a plurality of base station transmitters for the purpose of OTD estimation enhancement, and transmit identical reference signals from the plurality of base station transmitters, the reference signals being identical both in the signal sequence and time-frequency resources used for transmission.

摘要： PURPOSE:To find the phase difference between 8.2f (f; fundamental frequency) signals from a master and a slave station at a receiver and to obtain the titled device at low cost without spoiling its function, by transmitting a 8.2f signal phase-locked to the main station from the main station and each slave station at different time for a specific time shorter than the transmission time of an 8.2f signal used for time synchronization in the pause of an 8.2f signal. CONSTITUTION:A phase discriminator 5 and a master station VCO7 are connected together during master station transmission and each slave station VCO and the phase discriminator 5 are connected together during the transmission of each slave station; the master station VCO7 is phase-locked with an 8.2f signal from the master station and respective slave station VCOs 8-10 are not phase-locked with 8.2f signals from respective slave stations. The output of the master station VCO7 phase-locked with the 8.2f signal from the master station is inputted to a phase difference measuring instrument 12 and the outputs of slave station VCOs 8-10 phase-locked with 8.2f signals from the slave stations are switched by multiplexers 11 at respective slave stations during 8.2f signal transmission and inputted to the phase difference measuring instrument 12 to find phase differences between the master station VCO7 and respective slave station VCOs 8-10, displaying them on a phase difference display meter 13.
