[1] [2] This is equivalent to convolving the unknown signal with a conjugated time-reversed version of the template. Maximum Likelihood Estimation Open Live Script The mle function computes maximum likelihood estimates (MLEs) for a distribution specified by its name and for a custom distribution specified by its probability density function (pdf), log pdf, or negative log likelihood function. maximum entropy. f. This book, an essential guide for understanding the implementation aspects of a digital modulation system, shows how to simulate and model a digital channel output, the receiver uses a procedure known as detection to decide which message, or sequence of messages, was sent. This chapter characterizes and analyzes optimumdetection for a single message transmission through the channel.
