Abstract
Some promising technologies such as Internet-of-things (IoT) communicate by means of backscattered power to minimize power consumption. In backscatter-based communications, the fading of a signal envelope is, in general, worse than that of standard one-way communications. To concisely study fading in backscatter channels, we - in this paper - summarize the theory of spatial fading in backscatter channels in addition to derive an analytical expression for the Rician K-factor in the case of monostatic backscatter configurations. Furthermore, we rely on the bit-error-rate (BER) to establish an upper- and lower-bound limit for partially correlated backscatter channels. BER analyses reveal that at low signal-to-noise ratio (SNR), all backscatter configurations result in a similar BER if the underlying channels undergo either Rayleigh or Weibull fading.
