A two-state Rician model for predicting indoor wireless communication performance

The received signal amplitude of an indoor wireless channel is generally modeled as Rayleigh or Rician fading depending on the situation. In addition to these, other fading models including the Gilbert, two-state analog, and log-normal are used for fading channels in general. Bultitude [1987] found that his measurements of several indoor channels best fit the Rician model. The present authors describe a two-state Rician fading model that better matches Bultitude's data. For DPSK, the bit-error-rate performance of the two-state Rician model is worse than the pure Rician model by about 8 dB.
