Spreading of a pulse beyond its allotted time period Tb (pulse width) will tend to interfere with adjacent pulses. In digital transmission, ISI arises due to the dispersive nature of a communications channel. A pulse shape with this spectrum is the \ideal interpolation fllter" in signal processing, and corresponds to g(t) = sinc ¡ t T ¢ def = sin(…t T) …t T in the time domain (see Figure 4). The advantages of the sinc pulse are similar to the advantages of the rectangular pulse, except that they hold in the frequency domain rather than in the time domain.

Show this shows how the over the air waveform would look (in actuality we typically do half the pulse shaping in the transmitter with a root-raised cosine filter while this plot shows the result after the second root-raised cosine filter in the receiver), but in general we are seeing the amplitude and phase of the time domain waveform for all samples, and the job of the receiver is to determine the sampling locations where the red dots are shown (the center of each symbol), and we then

Digital commu-nication entails mapping digital information into electromagnetic energy (voltage waveforms) and transmitting over an appropriate physical medium (over a wire or wireless). This presentation briefly discusses application of the Root Raised Cosine (RRC) pulse shaping in the space telecommunication. Use of the RRC filtering (i.e., pulse shaping) is adopted in commercial communications, such as cellular technology, and used extensively.
