# Digital Compensation Techniques for Receiver Front-Ends

The great tragedy of science — the slaying of a beautiful hypothesis by an ugly fact.Thomas H. Huxley, 1825–1895.

^{104}^{1}

The digital signal processing aspects of an OFDM transceiver have been addressed in Chap. 4, where we achieved a low-cost, low-power, scalable solution based on digital VLSI design. This shifts the cost and performance pressure to the analog front-end.

An important cost factor in analog front-ends is a high number of heterogeneous components. For every component that designers remove from the bill of materials, a drop occurs in the overhead to maintain the supply chain, a drop occurs in manufacturing cost due to assembly, and most likely a reduction in size occurs due to increased integration [Moretti03b]. Heterogeneity and high component count originates from performance-oriented optimum selection of components. Today, a multiobjective optimization for performance, power consumption, size, and cost has come in place. This also requires changes in front-end...
