摘要：
In an ideal RC, the analytical expressions for the statistical distributions of the enhanced backscatter coefficient (e(b)) are derived. It has been found that the superposition of random variables with exponential distributions has a probability density function of Erlang distribution, and the distribution of the ratio of two random variables with Erlang distribution can be derived analytically, which is the distribution of the enhanced backscatter coefficient. The unbiased estimator of eb is also given with and without approximations. Measurements have been performed to verify the results.
