| Summary: | 碩士 === 國立暨南國際大學 === 電機工程學系 === 97 === In this thesis, the design procedure for the cell planning of high speed rail (HSR) communication system that is based on OFDM is discussed. Adaptive modulation and coding (AMC), path loss between the train and base station (BS), and link budget are considered. To obtain a cell coverage area that can provide a stable data transmission rate, simple switch over and straight small cell structure is adopted. Using the channel quality between the train and base station, system bandwidth, carrier frequency, modulation scheme, guard period, subcarrier number, BS transmitted power, antenna gain, etc. In this thesis a systematic cell planning design procedure is proposed, it decides the cell size and provides a stable data transmission rate.
