Since then programmable logic arrays, standard cell, macrocells, module compilers, gate arrays, and reconfigurable hardware have steadily helped to ease the time and cost of mapping a function onto silicon. Today semiconductor technology allows the integration of a wide range of complex functions on a single die, the SoC concept already mentioned. 13 µm chips, mask costs of $600,000 are not uncommon); ii) increase performance predictability reducing the risk involved in complex SoC design and manufacturing as a re- 1.

The basic idea underlying this early spread spectrum concept consists in partitioning the overall spectrum into K separate channels or bands (also referred to as frequency bins), all having the same bandwidth as the signal to be transmitted. Spectrum spreading is achieved by transmitting the (conven- 28 Chapter 2 tional) narrowband signal into one bin for a given time interval Thop , and then by randomly changing the carrier frequency of the modulator so as to place the signal spectrum in another bin, and so forth.
