  • This paper presents a new method for finding the Block Pulse series coefficients, deriving the Block Pulse integration operational matrices and generalizing the integration operational matrices which are necessary for the control fields using the Block Pulse functions. In order to apply the Block Pulse function technique to the problems of state estimation or parameter identification more efficiently, it is necessary to find the more exact value of the Block Pulse series coefficients and integral operational matrices. This paper presents the method for improving the accuracy of the Block Pulse series coefficients and derives the related integration operational matrices and generalized integration operational matrix by using the Lagrange second order interpolation polynomial.

  • 해상관제서비스(VTS, Vessel Traffic Service)에서 사용되는 대부분의 해상감시레이더(SSR, Sea Surveillance Radar)는 마그네트론 기반의 Non-Coherent 방식이 사용되고 있으며, 표적에 대한 탐지 성능을 만족시키기 위하여 신호 대 잡음비(SNR, Signal to Noise Ratio) 개선 기능이 있는 펄스 적분(Pulse Integration) 기법을 사용하고 있다. 특히, 펄스 적분 기법은 신호 대 잡음비의 개선을 통하여 표적 탐지 성능에 중요한 영항을 미칠 뿐만 아니라, 신호 간섭(Interference) 및 스파이크 잡음(Noise Spike)을 개선하는 효과를 갖는다. 본 논문에서는 Non-Coherent 레이더를 사용하는 VTS 시스템에 펄스 적분 기법을 적용하기 위해 MATLAB을 이용한 모의실험을 수행하고, 자주 사용되는 펄스 적분 기법들 간의 성능 분석을 통해 최적의 펄스 적분 기법을 검증하고자 한다.

  • 본 논문에서는 레이더 시스템에서 단일 펄스 방식, 집적 상관 방식, 비 집적 상관 방식의 신호대 잡음비 성능에 대해서 비교 분석하였다. 그리고, 공간상에 두 목표물에 대한 방향을 추정하여 기존의 방법과 비교 분석하였다. 레이더 시스템에서 일반적으로 반사파와 전송파의 왜곡을 방지하고 감소시키기 위해서 펼스파를 이용하여 신호를 전송한다. 본 논문에서는 수신신호를 처리하는 방식으로 포락선 검파기 앞에서 처리하는 집적 상관방식과 과 포락선 검파기 뒤에서 처리하는 비 집적 상관 방식의 성능을 비교 분석하였다. 모의실험을 통하여 목표물 방향을 추정하였고, 두 목표물의 탐지 거리를 추정하여 신호대 잡음비 성능을 비교 분석하였다. 집적 상관방식의 성능이 우수함을 입증하였다.

  • This paper proposes a medium access control (MAC) protocol for multiple-input multiple-output (MIMO) ad-hoc networks. Multiple-packet receptions in MIMO systems have attracted as a key technique to achieve a high transmission rate. In the conventional protocols for multiple-packet receptions, timing offsets among multiple-frame transmissions cause frame collisions induced by hidden nodes, which degrades network performance. In the proposed protocol, transmission synchronization among hidden nodes can be achieved by applying pulse/tone exchanges. By applying the pulse/tone exchanges, multiple-packet receptions among hidden nodes can be achieved, which enhances network throughputs compared with the conventional protocol. Simulation results show effectiveness of the proposed protocol.

  • Objectives : To understand the theoretical principle of the pulse patterns listed in the 27 Pulses chapter in the Donguibogam, to further examine the relationship between the pattern and according disease of each pulse. Based on these findings, the fundamental meaning of Heo's theories and specific characteristics of the seven exterior pulses were understood. Methods : First, the 27 Pulses chapter of Heo Jun and Zhenmaimun chapter of Lichan were compared. Next, the Chandomaekgyeol and the Maijing were compared to determine bibliographical evidence of Heo's integration of pulse patterns. Based on the main references, the relationship between pattern and disease were studied, along with cases where the principles of the 27 pulses were applied in the Maekbeob chapter of the Donguibogam. Results & Conclusions : In the 27 Pulses chapter, Heo undertook the task of integrating the pulse patterns based on the differentiation of the excessive type and deficient type, along with the awareness of the issue of pulse pattern and disease matching. In specific, he organized and integrated the linguistic expressions of pulses in major pulse texts, directly intervening in places that he felt needed additional explanation. In conclusion, we found that the 27 pulses are systematic, rational, and unique in terms of pulse integration.
