However, this approach is completely impractical for calculations on an ensemble of spins that are subject to multiple excitation pulses in typical NMR experiments. Consequently, we

istence of such a peak indicates that the participating spins are coupled to one other by scalar (J) coupling through chemical bonds or via dipolar coupling through space. The position of the peak is defined by the chemical shifts, or resonance frequencies, of the coupled spins..In this chapter we w

Digital Modulation: The Basic Principles, study in this chapter, along with some issues involved in their realization. In these methods, baseband signals linearly modulate an RF carrier. Ideally, we would like to cut to the chase and study these methods immediately. This is not what we will do, however. First the fundamentals of baseband t

Such a channel, for example, may be one that adds noise, or interference, or unwanted nonlinearities. In this chapter we focus on error detection and error correction coding as applied

Multi-Carrier-Based Multiple-Access Techniques,plies communication via a plurality of radio-frequency carriers, normally referred to as subcarriers. In this chapter we explore multi-carrier-based multiple-access techniques as applicable to 5G NR. First, we review orthogonal frequency division multiplexing (OFDM). OFDM is a multi-carrier techniqu
