Abstract
In this paper, the performances of various channel estimation schemes for DVB-H system are investigated. The linear interpolation, the second order interpolation, the cubic spline interpolation, and the time-domain interpolation, which are used in frequency domain, are chosen as the channel estimation schemes. We derived the performances of Mean Square Error (MSE), Bit Error Rate (BER), and the complexity of calculation in Rayleigh and Rician fading channel through computer simulations. From the simulation results, the cubic spline interpolation shows the best performance under high
본 논문에서는 유럽의 DVB-H (Digital Video Broadcasting-Handheld) 시스템을 위한 여러 채널 추정 기법의 성능을 분석하였다. 채널 보상 기법으로는 주파수 영역에서 사용되는 선형 보간법, 이차 보간법, cubic-spline 보간법, time-domain 보간법을 사용하였고, 레일리와 라이시안 페이딩 채널 환경에서 시뮬레이션을 통해 MSE (Mean Square Error)와 BER (Bit Error Rate) 성능과 연산의 복잡도를 비교, 분석하였다. 시뮬레이션 결과 높은
