Asymptotic rate-distance function
= Asymptotic rate-distance function
{title2=$\alpha_q(\delta)$}
The asymptotic rate-distance function is $\alpha_q(\delta)=\limsup_{n\to\infty}n^{-1}\log_q A_q(n,\max\{1,\lceil\delta n\rceil\})$. It is the best asymptotic <code rate> available at the specified <relative minimum distance>. A limsup is used because the definition does not assume an ordinary limit exists.
