echo equation

First, prefaceAs a result of the work, the author has been in contact with Echo cancellation (echo cancellation) technology since 2004, and has been engaged in the work related to echo cancellation technology in a large communications company, and

First, because of the work of the relationship, the author since 2004 contact Echo cancellation (echo cancellation) technology, and has been engaged in a large communications enterprises with ECHO cancellation technology related work, the echo

From the reason of communication echo, can be divided into acoustic echo (acoustic echo) and line echo (lines echo), the corresponding echo cancellation technology is called acoustic echo cancellation (acoustic echo cancellation, AEC) and line echo

How does PHP find the root of a quadratic equation ?. Today, someone has a mathematical question: 4x + 1x2. how much is x. Converting the equation, 4x2 + 12x, and then 4x2 + 2x + 10, is actually a problem of the unary quadratic equation. For a long

First, prefaceto understand echo cancellation technology, we have to mention the theory of digital signal processing as the theoretical basis of modern communication technology. First of all, there is an important branch of the digital signal

This assumes that the reader has the basic knowledge of adaptive filters. The AEC of Speex is based on NLMs, which is realized by MDF frequency domain, and finally derives the optimal step estimation: The ratio of residual echo to error. The optimal
