Whether working in wireless communication technology or radar/sonar systems, researchers and engineers must understand the fundamentals of signal detection. While offering a clear, self-contained treatment of the theory behind signal detection, the author incorporates many applications and wide-ranging examples that demonstrate how to apply the concepts to real-world problems. Accessible to senior level undergraduates and suitable as both a text and a reference, this book incorporates treatments of modern concepts, methods, and technologies, including digital signal processing, wavelets, fast Fourier transform processing, and cyclostationary processing.
