  In this paper we introduce a new probabilistic model for optimizing erasures
occurring in data transmission using Parseval frames and a sequence of
Bernoulli random variables associated to the channels of the transmission. We
establish several results characterizing the optimal Parseval frames for our
model. We show also that compared to existing models
\cite{holmes2004optimal,casazza2003equal,leng2013probability,li2018frame}, our
model gives better performance.
