This book treats the topic of extending the adaptive filtering theory in the context of massive multichannel systems by taking into account a priori knowledge of the underlying system or signal. The starting point is exploiting the sparseness in acoustic multichannel system in order to solve the non-uniqueness problem with an efficient algorithm for adaptive filtering that does not require any modification of the loudspeaker signals.
The book discusses in detail thederivation of general sparse representations of acoustic MIMO systemsin signal or system dependent transform...

Securing VoIP: Keeping Your VoIP Network Safe will show you how to take the initiative to prevent hackers from recording and exploiting your company's secrets. Drawing upon years of practical experience and using numerous examples and case studies, technology guru Bud Bates discusses the business realities that necessitate VoIP system security and the threats to VoIP over both wire and wireless networks. He also provides essential guidance on how to conduct system security audits and how to integrate your existing IT security plan with your VoIP system and security plans,...

This work addresses stealthy peripheral-based attacks on host computers and presents a new approach to detecting them. Peripherals can be regarded as separate systems that have a dedicated processor and dedicated runtime memory to handle their tasks. The book addresses the problem that peripherals generally communicate with the host via the host's main memory, storing cryptographic keys, passwords, opened files and other sensitive data in the process - an aspect attackers are quick to exploit.

Here, stealthy malicious software based on isolated micro-controllers is implemented to...

Since the release of the first internet phone in 1995, the use of voice over internet protocol (VoIP) has grown exponentially, so that today it is an established and popular technology for real-time communications in both business and daily life.

This Guide to Voice and Video over IP introduces the fundamental techniques underpinning the huge success and global penetration of VoIP. After highlighting the benefits and growing importance of VoIP, the text presents a review of the latest advances in speech and video compression, computer networking protocols, the assessment and...

How did popular radio in past decades from President Franklin D. Roosevelt's "Fireside Chats" in the 1930s through Top 40 music and Rush Limbaugh's talk radio empire shape American society? How did devices and systems like the iPhone, Pandora, and YouTube turn the radio industry upside-down? Does radio still have a future, and if so, what will we want it to look like?

Radio 2.0: Uploading the First Broadcast Medium covers the history and evolution of Internet radio, explaining what came before, where Internet radio came from, and where it is likely headed. It also gives...
