Performance analysis of spread-spectrum multiple-access with DPSK modulation in indoor wireless communications systems

The performance of a direct-sequence code division multiple-access (DS-CDMA) with differential phase shift-keying (DPSK) modulation in an indoor radio communications environment which is characterized by either Rayleigh or Rician fading multipath channels is analyzed. This paper illustrates the use of importance sampling as a computationally efficient and accurate tool for computer-aided design and analysis of CDMA in indoor wireless communications systems.
