    • Provided is a distance estimation apparatus, system and method for accurately estimating the distance between TX/RX devices by means of low-end hardware in a communication system such as the IEEE 802.15.4a system. The distance estimation apparatus includes an analog-to-digital converter, a parallelizer, a parallel synchronization means, a counter, and a system clock generator. The analog-to-digital converter analog-to-digital converts a received packet signal to generate a serial digital signal, and the parallelizer 1:N parallelizes the serial digital signal. The parallel synchronization means includes an N number of buffers for receiving the output of the parallelizer. A counter outputs a count value for estimation of the propagation delay time of a UWB signal on the basis of the sampling data retained in the parallel synchronization means. The system clock generator generates a system clock in the distance estimation apparatus. Therefore, it is possible to accurately estimate the distance between the TX/RX devices by arithmetically calculating a received signal while operating a ranging counter with a low-rate system clock, thereby simplifying the hardware structure and minimizing power consumption.
    • 提供了一种距离估计装置,系统和方法,用于通过诸如IEEE 802.15.4a系统的通信系统中的低端硬件来精确地估计TX / RX设备之间的距离。 距离估计装置包括模数转换器,并行器,并行同步装置,计数器和系统时钟发生器。 模数转换器模数转换接收到的分组信号以产生串行数字信号,并行化器1:N并行串行数字信号。 并行同步装置包括用于接收并行化器的输出的N个缓冲器。 计数器基于保持在并行同步装置中的采样数据输出用于估计UWB信号的传播延迟时间的计数值。 系统时钟发生器在距离估计装置中产生系统时钟。 因此,通过在运行具有低速率系统时钟的测距计数器的同时计算接收信号,可以精确地估计TX / RX设备之间的距离,从而简化硬件结构并最大限度地降低功耗。

    • 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.

    • Disclosed herein is a method of analyzing load-settlement characteristics of a top-base foundation. The method includes the step of inputting properties of a material of a top base, a basic size of footing configuration, and a load of a structure, the step of inputting the kind of ground and a base ground thickness, the step of determining an influential depth and a load dispersion angle depending on the kind of ground, the step of inputting properties of the ground, the step of determining an immediate settlement amount of the ground, and the step of determining a total settlement amount. The method according to the present invention can precisely determine settlement taking into account footing configuration. Furthermore, the method calculates the settlement taking into account consolidation settlement when the ground is cohesive soil ground or top-cohesive-soil and bottom-sandy-soil ground. Thus, the settlement can be precisely determined.
