CS3282: Digital Communications ’05-06 Section 6: Inter-symbol interference and pulse shaping Rectangular symbols are not suitable for transmitting data at the highest possible bit-rates over band-limited channels. A rectangular pulse or any other shaped pulse which is time-limited (i.e. is non-zero

A pulse shaping filter is used in communication channels to manipulate a waveform or pulses to have the desired shape in the time domain. A pulse shaping filter can be a physical circuit, but normally it’s a mathematical function that is used as a signal processing algorithm. We present Nyquist pulse shaping conditions for two-dimensional (2-D) digital communication systems to be free from inter-symbol interference, for general regular sampling grids. We provide examples of 2-D pulse functions satisfy-ing these Nyquist conditions. In particular, we show that a family of 2-D pulse functions that we construct as separable Index Terms—pulse-shaping, eye-diagram, roll-off factor, ISI, channel noise, image quality I. INTRODUCTION Digital Communication System plays an important role in today’s world and this project sheds light on the shortcomings of digital transmission. By taking an example of an image the project demonstrates the effect of pulse-shaping and Here you can download the free lecture Notes of Data Communication Pdf Notes – DC Notes Pdf materials with multiple file links to download.

The Data Communication Notes pdf (data communication lecture notes) book starts with the topics covering Model of Digital Communication Systems, PCM Generation and Reconstruction, Introduction, ASK,ASK Modulator, Pulse shaping for optimum transmissions The above plots and descriptions used Raised Cosine (and Root-Raised Cosine) pulse shaping but an alternate harris-Moerder filter is described in this paper http://eon.sdsu.edu/~seshagir/SDR05.pdf. Using this as the pulse shaping filter results in an order of magnitude lower EVM for the same number of taps.

Pulse shaping is a spectral processing technique by which fractional out of band power is reduced for low cost, reliable, power and spectrally efficient mobile radio communication systems. It is

These sudden jumps create high sidelobes in frequency domain which makes co-existence of various wireless systems inefficient. Q2. the pulse causes its shape to change from purely rectangular to a smooth contour without sharp edges. Therefore, the act of filtering rectangular data pulses is often referred to as pulse shaping. Unfortunately, limiting the bandwidth of the rectangular pulse necessarily introduces a damped oscillation.
