Digital commu-nication entails mapping digital information into electromagnetic energy (voltage waveforms) and transmitting over an appropriate physical medium (over a wire or Pulse Shaping: Intersymbol Interference (ISI)  The process of residual signals at the receiver output due to other symbols interfering with the required symbol is known as intersymbol interference.  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. 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.

Ee521 Analog And Digital Communications PPT. Presentation Summary : Today some topics will be presented on the whiteboard. The slides will be updated on the web site in a few days. EE521 Analog and Digital Communications Microwave and Digital communication Lab 3 THEORY: Pulse modulation: A form of modulation in which a pulse train is used as the carrier. Information is conveyed by modulating some parameter of the pulses with a set of discrete instantaneous samples of the messages signal. The minimum sampling and aging. Therefore, digital pulse-shaping filters have become an integral part of many digital data transmission systems. This application note describes the fundamentals of pulse shaping and the tradeoffs associated with the design of digital pulse-shaping filters.

• Overall frequency response “raised-cosine (RC) spectrum”, which made up of transmit filter, channel and receiver filter Perhaps the most common pulse-shaping filter type used in communication systems is the Raised Cosine or Root Raised Cosine filter. The name comes from the shape of the spectral response, where the transition band of the filter follows a half-cycle of a raised cosine shape.
