详细说明： Abstract. In this article an OFDM system without the necessity of a cyclic prefix is presented. First a generalised data model that describes different mobile radio systems by a set of parameters is developed. That model is taken as a basis to perform data detection general enough to be applicable in different mobile radio systems. The differences and similarities of different systems with regard to the data model are elaborated. It comes out that in order to enable common detection strategies the cyclic prefix in OFDM based sys tems can be discarded, which implies that the information data rate is increased. The price is a higher computational requirement of the receiver. Following the desire not to increase the computational requirements for data detection significantly a technique is found to perform data detection in OFDM systems without cyclic prefix causing only a moderate increase in computational requirements. ...展开收缩
