Question: In 3GPP BER/BLEER tests for TDD, what statistical distribution is used when the number of samples (ns) is fixed and the number of errors (ne) is counted to calculate BER/BLEER?
Option 1: Chi Square Distribution with degree of freedom ns
Option 2: Poisson Distribution with average NE (Number of Errors)
Option 3: Normal Distribution with mean NE and standard deviation sqrt(NE)
Option 4: Binomial Distribution with parameters ns and error probability p
Explanation: According to the 3GPP specifications for TDD, when counting errors after a fixed number of samples (ns), the Poisson Distribution is used, characterized by its average (NE: Number of Errors), suitable for measuring error occurrences in known trials.
