Compatibility Analysis between Wideband Code Division Multiple Access (WCDMA) Service and Global Mobile Personal Communication by Satellite (GMPCS)

Due to explosive demand for wireless service and limited frequency spectrum resource, an efficient use of frequency spectrum has been a critical issue for making a full use of available frequency bands. In this paper, we analyze the compatibility between wideband code division multiple access (WCDMA) and the global mobile personal communication by satellite (GMPCS) which is investigated by analyzing interference from each system. These two adjacent services may cause harmful interference each other. In order to avoid interference between the systems, they have to keep a proper separation in distance or limited power as low as possible. This paper analyzes compatibility between W-CDMA and GMPCS systems for efficiency use of frequency band through theoretical analysis and simulation tool.
