英文摘要	Adapted parameters of OFDM signals can bring performance improvement in mobile satellite communications. This paper firstly analyzes the effect of cyclic-prefix (CP) length and subcarrier bandwidth on system interference and capacity. This effect can be described by a formula which consists of system capacity, CP length and sub-carrier bandwidth. Then using this formula, a method to select the optimal parameters is given. In the end, a numerical calculation is performed to figure out the optimal parameters, considering the multipath delay spread and Doppler spread in satellite channel. It comes up that in satellite channel the CP is not very effective to improve the system performance and a wider sub-carrier bandwidth is desired. ?
