Abstract :
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. TCDMA 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 μs as analog matched filters (MFs) in the receiver. The indoor multipath fading channel is modeled taking into account previous measurement results for investigation of the TCDMA system capacity
