OBJECTIVES This purpose of this paper is to introduce the status of the Asan Medical Center (AMC) medical information system with respect to healthcare quality improvement. METHODS Asan Medical… (More)
The paper proposes a practical method for AGC (automatic gain control) in an HPI (high-speed portable Internet) system. Downlink packets in this system consist of preamble symbols for AGC, AFC… (More)
This paper proposes an efficient AGC scheme before mobile synchronization only using the existing hard-ware engine for AGC scheme after synchronization.
In this paper, we analyzed the available frame synchronization error ranges through the uncoded BER (bit error rate) performance in the condition of 64-QAM digital modulation in Mobile-WiMAX system.
Poly[N-pvinylbenzyl-O-D-galactopyranosyl-(1-4)-D-glucoamide], poly[N-pvinylbenzyl-O-D-glucopyranosyl-(1-4)-D-glucoamide], and poly[N-p-vinylbenzyl-O-mannopyranosyl-(1-4)-D-gluconamide] (referred to… (More)
The time-variation of channels during one OFDM symbol destroys the orthogonality among subcarriers and results in intercarrier interference (ICI), which may detail substantial error performance.… (More)
Generally in real implementation of OFDM system, the simple and fast LS channel estimation method has been used for the wireless channel in the OFDM systems. If the wireless channel environment were… (More)
This paper finds the optimum input bit size of FFT engine in WiBro system through the uncoded-BER performances of computer simulation.
