This authored monograph presents key aspects of signal processing
analysis in the biomedical arena. Unlike wireless communication systems,
biological entities produce signals with underlying nonlinear, chaotic
nature that elude classification using the standard signal processing
techniques, which have been developed over the past several decades for
dealing primarily with standard communication systems. This book
separates what is random from that which appears to be random and yet is
truly deterministic with random appearance. At its core, this work gives
the reader a perspective on biomedical signals and the means to classify
and process such signals. In particular, a review of random processes
along with means to assess the behavior of random signals is also
provided. The book also includes a general discussion of biological
signals in order to demonstrate the inefficacy of the well-known
techniques to correctly extract meaningful information from such
signals. Finally, a thorough discussion of recently proposed signal
processing tools and methods for addressing biological signals is
included. The target audience primarily comprises researchers and expert
practitioners but the book may also be beneficial for graduate students.
