- W949408055 abstract "This chapter examines various characteristics of short-range systems. It highlights several methods of encoding the one's and zero's of the baseband information before modulation to meet certain performance requirements in the receiver, such as constant DC level and minimum bit error probability. The chapter describes analog systems and observes that the pre-emphasis/de-emphasis and compression/expansion circuits in voice communication devices improve the signal-to-noise ratio and increase the dynamic range. Reasons for preferring frequency or amplitude digital modulation are presented from the points of view of equipment complexity and of the different regulatory requirements in the US and in Europe. Similarly, there are several considerations in choosing a frequency band for a wireless system, such as background noise, antenna size, and cost. The three basic modulation types involve impressing the baseband data on the amplitude, frequency, or phase of a radio frequency (RF) carrier signal. Modern digital communication uses combinations and variations in the basic methods to achieve high bandwidth efficiency, or conversely, high signal-to-noise ratio with relatively low power. The chapter presents an introduction to quadrature modulation and to the principles of spread-spectrum communication. The importance of advanced modulation methods is on the rise, and they can surely be expected to have an increasing influence on short-range radio design in the near future." @default.
