Application of saw matched filters for time code division multiple access (TCDMA) systems

To improve the system performance and capacity it is important for wireless mobile radio communication systems to take the advantages of various multiple access technologies. According to the indoor radio channel characteristics we describe a multiple access scheme - the Time Code Division Multiple Access (TCDMA) for indoor wireless applications with a carrier frequency of 2.4 GHz. TCDTMA combines the advantages of both Time Division Multiple Access (TDMA) and Code Division Multiple Access (CDMA). For implementation of a TCDMA system we use Surface Acoustic Wave (SAW) devices with delays less than 5 Cls as analog Matched Filters (MF's) in the receiver [1]. The indoor multipath fading channel is modeled taking into account the measurement results from [4, 5, 7] for investigation of the TCDTMA system capacity.
