OFDM The basic concept of OFDM was first proposed by R. W. Chang [see Ref 3], recognizing that bandlimited orthogonal signals can be combined with significant overlap while avoiding interchannel interference. Figure 1: The analog communication system But, before you start shooting the arrow in the dark, you must know the basic concepts of digital marketing. Basics of Fiber Optics Mark Curran/Brian Shirk Fiber optics, which is the science of light transmission through very fine glass or plastic fibers, continues to be used in more and more applications due to its inherent advantages over copper conductors. The source output may be either an analog signal, such as an audio or video signal, or a digital signal, such as the output of a teletype machine, that is discrete in time and has a finite number of output characters. Digital radio, is the transmitted of digital modulated analog We start with a discussion of a basic digital communications link, cover the most commonly used clocking architectures, discuss line-coding methods, and conclude with special techniques for high-speed serial transmission systems. Hopefully, this chapter will enlighten you as to the basics of digital communication, its advantages, disadvantages, and practical considerations. The basic blocks of an analog communication system are given in Figure 1. Write down the modules involved when driving into a petrol station to fill the car, pay the cashier and depart.

We'll discuss the communication structure and the required digital lines. DigitalMessages Early long-distance communication was digital semaphores, white flag, smoke signals, bugle calls, telegraph Teletypewriters (stock quotations) Baudot (1874) created 5-unit code for alphabet. The functional blocks at the receiver perform the reverse process to retrieve the original message [2]. The functional blocks at the transmitter are responsible for processing the input message, encoding, modulating, and transmitting over the communication channel. in Figure 4.2-2a the a priori probabilities are equal for the two possible messages, and the decision threshold A/2 given by (4.2.4) falls halfway between zero and A A digital communication system consists of six basic blocks. 174 These conditional probabilities are plotted in Figure 4.2-2, but are scaled by the a priori probabilities P 1 the show how the possible voltages v are assigned to the two regions V 1 and V 2 in accord with (4.2.4). Digital Communications I Slide 3-13 Exercises 3-1 Abstraction is a form of breaking a problem down into constituent parts. Now, we shall discuss the functioning of these blocks.
