Download Principles of Speech Coding by Tokunbo Ogunfunmi PDF

By Tokunbo Ogunfunmi

It is changing into more and more obvious that each one sorts of communication—including voice—will be transmitted via packet-switched networks according to the web Protocol (IP). accordingly, the layout of contemporary units that depend upon speech interfaces, equivalent to cellphones and PDAs, calls for an entire and up to date figuring out of the fundamentals of speech coding.

Outlines key sign processing algorithms used to mitigate impairments to speech caliber in VoIP networks

Offering a close but simply obtainable creation to the sphere, Principles of Speech Coding presents an in-depth exam of the underlying sign processing recommendations utilized in speech coding. The authors current coding criteria from numerous organisations, together with the foreign Telecommunication Union (ITU). With a spotlight on purposes resembling Voice-over-IP telephony, this accomplished textual content covers contemporary learn findings on themes including:

  • A normal advent to speech processing
  • Digital sign processing concepts
  • Sampling conception and comparable topics
  • Principles of pulse code modulation (PCM) and adaptive differential pulse code modulation (ADPCM) standards
  • Linear prediction (LP) and use of the linear predictive coding (LPC) model
  • Vector quantization and its purposes in speech coding
  • Case experiences of functional speech coders from ITU and others
  • The web low-bit-rate coder (ILBC)

Developed from the authors’ mixed teachings, this booklet additionally illustrates its contents via delivering a real-time implementation of a speech coder on a electronic sign processing chip. With its stability of idea and functional insurance, it really is perfect for senior-level undergraduate and graduate scholars in electric and laptop engineering. it's also compatible for engineers and researchers designing or utilizing speech coding platforms of their work.

Download Rediscovering the World: Map Transformations of Human and by Benjamin Hennig PDF

By Benjamin Hennig

‘We want new maps’ is the valuable declare made during this publication. In a global more and more prompted by way of human motion and interplay, we nonetheless count seriously on mapping suggestions that have been invented to find unknown areas and discover our actual setting. even supposing the conventional proposal of a map is at the moment being revived in electronic environments, the underlying mapping techniques aren't in a position to making the complexity of human-environment relationships absolutely understandable. ranging from how humans may be wear the map in new methods, this ebook outlines the improvement of a singular procedure that stretches a map in response to quantitative information, similar to inhabitants. the hot maps are known as gridded cartograms because the process relies on a grid onto which a density-equalising cartogram approach is utilized. The underlying grid guarantees the upkeep of a correct geographic connection with the genuine global. It permits the gridded cartograms for use as basemaps onto which different details will be mapped. this is applicable to any geographic info from the human and actual surroundings. As proven throughout the examples provided during this ebook, the recent maps are usually not restricted to exhibiting inhabitants as a defining point for the transformation, yet can exhibit any quantitative geospatial facts, reminiscent of wealth, rainfall, or maybe the environmental stipulations of the oceans. the hot maps additionally paintings at quite a few scales, from a world viewpoint right down to the size of city environments. The gridded cartogram process is proposed as a brand new worldwide and native map projection that may be a achievable and flexible replacement to different traditional map projections. The maps according to this system open up a variety of power new purposes to rediscover the various geographies of the realm. they've got the aptitude to permit us to achieve new views via specific cartographic depictions.
