In modern digital communication systems, pulse-shaping filters allow the transmission of pulses with negligible intersymbol interference [1][2][3][4]. This means that pulse-shaping digital filter is a useful means to shape the signal spectrum and avoid interference of ultra wideband (UWB) to other legacy narrow band signals [5].

This paper. A short summary of this paper. Pulse / Spectrum Shaping in Fiber Optic Communications. 2019-09-30 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. That is, the In digital, or discrete, communication systems a broad class of symbol pulse shapes is used in order to obtain a zero-ISI characteristic.

Digital transmission system consists of: • The modulator is based on: • The symbol mapper takes bits and converts them into symbols a n) – this is done based on a given table • Pulse Shaping Filter generates the Gaussian pulse or waveform ready to be transmitted (Baseband signal) … The above equation states that the input sequence of uncorrelated binary sequence {a k} is changed into a sequence of correlated three level pulses {c k}. This correlation between the pulses may be understood as introducing ISI in the transmitted signal in an artificial manner.

Basic digital signals are rectangular with sudden jumps to values of +1 and -1 according to the binary data. These sudden jumps create high sidelobes in frequency domain which makes co-existence of various wireless systems inefficient.

ROLE OF PULSE SHAPING IN COMMUNICATION SYSTEMS In communication systems, data is transmitted as binary bits (ones and zeros). It is easier to implement a binary system using switches, where turning on a switch represents ’1′ and turning it off represents ’0′. Pulse shaping plays a crucial role in spectral shaping in the modern wireless communication to reduce the spectral bandwidth. Pulse shaping is a spectral processing technique by which fractional Recursive algorithms for real-time digital pulse shaping in pulse height measurements have been developed. The differentiated signal from the preamplifier (exponential pulse) is amplified and then digitized.

Fiber optic communication is band limited and typically occurs over the C-band. As modulation rates for optical signals increase each channel occupies more BW in the ELEC3203 Digital Coding and Transmission – MODEM S Chen Pulse Shaping — Starting Point • Unless transmission symbol rate fs is very low, one cannot use impulse, narrow pulse or rectangular pulse to transmit data symbols – Such pulses have very large (inﬁnite) bandwidth, but we only have ﬁnite baseband bandwidth B pulse-shaping load between the trans-mitter and receiver. It’s better in digital Before the advent of digital filter design, pulse-shaping filters had to be implemented as analog filter designs. Digital filters, however, offer several advantages of analog designs.
