Abstract :
This paper proposes an importance sampling methodology based on large deviations theory for the error floor assessment of a class of open-loop receivers with random carrier phase tracking in additive white Gaussian noise channels. Our simulations exhibit remarkable time gains when compared with conventional Monte Carlo
