Noise Reduction and Echo Cancellation in Communications Systems
Embedded Star has a new article about using noise reduction and echo cancellation technology to develop better communications systems. Here's the intro:
It is estimated that over a third of the world's population spend time talking on mobile phones. The quality of that communication experience very much depends on the clarity of the voice that is heard at each end of the conversation. In an increasingly noisy world, it is easy to see that noise reduction and echo cancellation play a major role in helping mobile phone developers meet the expectations of this massive and demanding customer base.
Even away from this huge consumer driven market, people such as the emergency services and Formula 1 drivers depend on communication systems that can delivery clear voice communication even in the most extreme environments. This article discusses some of the issues faced by communication equipment developers and a few of the solutions that are applied to help them deliver a noise and echo free world.
