About this course:

Digital Signal Processing (DSP) has become the enabling technology for the signal-conditioning and signal-processing tasks performed in modern modulators and demodulators. These tasks include spectral shaping, matched filtering, narrow-band and base-band filtering, sample rate changes (interpolation and decimation), timing acquisition, carrier acquisition, automatic gain control, I-Q balancing, DC-canceling, channel equalization, spectral translation, direct digital synthesis of local oscillator, and sigma-delta requantization. In first- and second-generation implementations of DSP-based modems, the architecture and signal-flow have been virtual carbon copies of equivalent analog prototype designs. Next generation implementations have a significantly different structure, reflecting a more mature understanding of the capabilities of multirate DSP algorithms in which the sampling clock becomes a powerful processing tool. This course presents the structure, unique attributes and capabilities, and implementation considerations of standard multirate filter structures including polyphase, dyadic half-band, and Cascade Integrator-Comb (CIC). The course also reviews the functional tasks of modulators and demodulators, and identifies where and how multirate signal processing can be inserted in the signal flow paths to improve performance, enhance capabilities, and reduce cost of system implementation.
