- 초록
- Recent maturity of Long Term Evolution (LTE) system has raised interest in evaluating how efficiently LTE cells are deployed. Noting that the Modulation and Coding Scheme (MCS) index determines the quality of transmission, we analyze the temporal variation of the index of a user equipment. Adopting a widely used Markov assumption on the variation, we exploit a hidden Markov model to estimate transition probability matrices describing the stochastic behavior of the MCS index. In the estimation, we use the real-world measurement data via a recently introduced reliable platform which can decode the control channels of LTE downlink signal. Numerical examples validate our analysis by investigating stationary probabilities.
