This paper deals with the proposal and performance evaluation of a Fixed Microwave Communication (FMC) system that shares the same bandwidth with a wireless personal communication network. In particular, the focus here is on the case of an existing UMTS network for which a FMC system is considered to provide a wireless connection between a remote base station not having the possibility of a wired connection to the core network and a base station having this possibility (core network access point). This facility is of special interest in a dense urban environment or whenever a wired connection is prohibitive for service providers due to its implementation cost or lack of frequency spectrum. The mutual interference effects between the FMC and the existing UMTS systems are investigated by focusing on typical application scenarios. A receiving scheme where interference signals are firstly detected and then canceled from the other received signals is proposed. The performance for the two interfering systems has been evaluated in terms of bit error rate both by means of analytical approach and computer simulations. The obtained results clearly demonstrate the effectiveness of the proposed method, in particular by allowing an efficient bandwidth sharing between the FMC system and the existing UMTS network.

Abstract
This paper deals with the proposal and performance evaluation of a Fixed Microwave Communication (FMC) system that shares the same bandwidth with a wireless personal communication network. In particular, the focus here is on the case of an existing UMTS network for which a FMC system is considered to provide a wireless connection between a remote base station not having the possibility of a wired connection to the core network and a base station having this possibility (core network access point). This facility is of special interest in a dense urban environment or whenever a wired connection is prohibitive for service providers due to its implementation cost or lack of frequency spectrum. The mutual interference effects between the FMC and the existing UMTS systems are investigated by focusing on typical application scenarios. A receiving scheme where interference signals are firstly detected and then canceled from the other received signals is proposed. The performance for the two interfering systems has been evaluated in terms of bit error rate both by means of analytical approach and computer simulations. The obtained results clearly demonstrate the effectiveness of the proposed method, in particular by allowing an efficient bandwidth sharing between the FMC system and the existing UMTS network.I documenti in FLORE sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
