Abstract

Indoor environments for mobile radio communications provide special challenges due to the physical characteristics of the radio wave propagation. A hybrid access scheme (combining the advantages of both TDMA and wideband CDMA) called time code division multiple access (TCDMA) is proposed and investigated for indoor wireless communications. The indoor radio channel is modeled in terms of channel impulse responses by taking into account various indoor measurement results. Various simulation methods are used to reduce the computational complexity and to ensure the result accuracy. The simulation results of the system performance reveal the capability and the capacity of TCDMA in a typical indoor cell modeled as a multipath fading radio channel
