How is log likelihood calculated?

Uses of the Log-Likelihood Function

The basic AIC formula AIC = -2(log-likelihood) + 2K. Likelihood-ratio test: a hypothesis test to choose the best model between two nested models.

What is LLR in LTE?

The LTE Symbol Demodulator block demodulates complex data symbols to data bits or log likelihood ratios (LLR) values based on the modulation types supported by LTE standard TS 36.211 [1]. The block provides an architecture suitable for HDL code generation and hardware deployment.

What is the importance of log likelihood?

The log likelihood

This is important because it ensures that the maximum value of the log of the probability occurs at the same point as the original probability function. Therefore we can work with the simpler log-likelihood instead of the original likelihood.
