New Digital Communication - Pulse Shaping - After going through different types of coding techniques, we have an idea on how the data is prone to distortion and how the measures are taken to prevent it fr Pulse shaping (i.e., base-band filtering) can vastly improve the behavior of wired or wireless communication links in an electrical system. With that in mind, Circuit Cellar columnist Robert Lacoste explains the advantages of filtering and examines Fourier transforms; random non-return-to-zero NRZ signaling; and low-pass, Gaussian, Nyquist, and raised-cosine filters.

We focus on a Raised Cosine response, and i Pulse shaping and spectrum in LTE RF engineering is a trade off between: required radio spectrum (bandwidth), speed of data transmission (bit rates) and complexity of implementation. The pulse form used to modulate complex data symbols to the radio carrier frequency is the major element of this story. Femtosecond pulse shaping is a powerful technique used in ultrafast optics for the generation of ultrashort (femtosecond) laser pulses with complex temporal shapes.

Sinc pulse shaping. As suggested in the earlier post, the pulse shape that avoids ISI with the least amount of bandwidth is a sinc pulse of bandwidth . A pulse shape can provide zero crossing at other pulse intervals, but a slight timing jitter can cause the sampling instant to move from the optimal sampling point. Faster the pulse decays outside the pulse interval, lesser will be the impact of timing jitters on sampling of adjacent pulses. ABSTRACT. We review the field of femtosecond pulse shaping, in which Fourier synthesis methods are used to generate nearly arbitrarily shaped ultrafast optical wave forms according to user specification. An emphasis is placed on programmable pulse shaping methods based on the use of spatial light modulators.
