Modem Theory: An Introduction to Telecommunications

On the center of any sleek verbal exchange method is the modem, connecting the knowledge resource to the communique channel. this primary direction within the mathematical idea of modem layout introduces the speculation of electronic modulation and coding that underpins the layout of electronic telecommunications structures. a close remedy of middle topics is supplied, together with baseband and passband modulation and demodulation, equalization, and series estimation.

RF and Digital Signal Processing for Software-Defined Radio: A Multi-Standard Multi-Mode Approach

Software-defined radio (SDR) is the most popular sector of RF/wireless layout, and this identify describes SDR ideas, thought, and layout rules from the point of view of the sign processing (both on transmission and reception) played through a SDR method. After an introductory review of crucial SDR options, this booklet examines waveform production, analog sign processing, electronic sign processing, information conversion, phase-locked loops, SDR algorithms, and SDR layout.

Sampling theory and methods

Sampling concept and strategies provides the theoretical points of "Sample Surveys" in a lucid shape for the advantage of either undergraduate and submit graduate scholars of statistics. It assumes little or no historical past in likelihood conception. the writer provides intimately numerous sampling schemes, together with easy random sampling, unequal likelihood sampling, and systematic, stratified, cluster, and multistage sampling.
