Pulse shaping is performed in the transmit and receive filters of a communication system. The most common class of filters used for pulse shaping are Nyquist filters (1,2,3). Enhanced Pulse Shaping Filters For IEEE 802.11 OFDM WLANs 23 occurs at the 54th sample. At α=1, the SRRC pulse has its main side lobe at the 50th sample whereas that for RC occurs at the 51st sample. Hence, there is an average delay Pulse Shaping 26.

wireless communication standards like GSM, CDMA etc., use base band &n The relationship between data rate, bandwidth and noise was quantified by Shannon (1948) and marked a breakthrough in communications theory. Digital data:  In digital communication systems, data symbols are typically made up of a series of square pulses, in which each pulse is transmitted at an amplitude of one of at  EE5713 : Advanced Digital Communications.

its effect as a pulse-shaping filter in a qpsk modulated systemIn order to reduce the effect of Inter Symbol Interference (ISI) in a digital communication system, 

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. ECE 461: Digital Communication Lecture 8b: Pulse Shaping and Sampling Introduction Information is digital in today’s world but the physical world is still analog. Digital commu-nication entails mapping digital information into electromagnetic energy (voltage waveforms) and transmitting over an appropriate physical medium (over a wire or wireless). space telecommunication. Use of the RRC filtering (i.e., pulse shaping) is adopted in commercial communications, such as cellular technology, and used extensively. However, its use in space communication is still relatively new.

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 out of band power is reduced for low cost, reliable , power and spectrally efficient mobile radio Pulse shaping is the process of shaping pulses to be transmitted based on the symbols generated via modulation (Lab 3).

This is called the process of pulse shaping. BUT there is no actual pulse. This is cal called baseband. A wireless digital communication device having a pulse shaping network for pulse shaping digital signals before modulation is proposed. The pulse shaping network includes a shift register to which data to be modulated is supplied.

This limits the realization of very high data-rate digital communication systems.

In electronics and telecommunications, pulse shaping is the process of changing the waveform of transmitted pulses. Its purpose is to make the transmitted signal better suited to its purpose or the communication channel, typically by limiting the effective bandwidth of the transmission.

Use of the RRC filtering (i.e., pulse shaping) is adopted in commercial communications, such as cellular technology, and used extensively. However, its use in space communication is still relatively new.

This is a form of distortion of a signal, in which one or more symbols interfere with Correlative Coding. So far, we’ve discussed that ISI is an unwanted phenomenon and degrades the signal.
