چکیده
SUMMARY An ISI-free power roll-off pulse, the roll-off characteristic of which is tunable with one power parameter, is proposed. It is shown that the proposed pulse is advantageous in terms of the probability of error for pulse detection in the presence of a timing error among currently known good pulses, among which the raised cosine pulse, " better than " raised cosine pulse, and polynomial pulse are considered.

Sinc Exponential ISI-Free Pulse with Better Performance
In this manuscript, the sinc exponential pulse (SEP) is evaluated at the transmitter and receiver side by using different metrics. The impulse response of the SEP is derived, analysed, and compared with the traditional RC pulse. The SEP is characterized by introducing two new design parameters, adding degrees of freedom to optimize the pulse for a certain transmission scheme and roll-off factor...

The integration of wide variety of communication services is made possible with invention of 3G technology. Code Division Multiple Access 2000 operates on various RF channel bandwidths 1.2288 or 3.6864 Mcps (1x or 3x systems). It is a 3G system which offers high bandwidth and wireless broadband services but its efficiency is lowered due to various factors like fading, interference, scattering, ...
متن کاملEvaluation of Performance Metrics for QPSK Modulated Mobile Communication System Using Root Raised Cosine & Raised Cosine Pulse- Shaping Filters
Mobile communication system uses Quadrature Phase Shift Keying (QPSK) as one of the efficient digital modulation techniques. Pulse-shaping technique plays an important role in digital transmission. Root-Raised Cosine (RRC) and Raised Cosine (RC) filters are two important pulse-shaping filters used in mobile communication system. In this paper we have presented the study of some useful parameter...
متن کاملOptical sinc-shaped Nyquist pulses with very low roll-off generated from a rectangular frequency comb
High-quality optical sinc-shaped Nyquist pulses with a virtual zero roll-off factor are obtained from the generation of a phase-locked, rectangular-spectrum frequency comb. Tunability over more than 4 frequency decades is demonstrated with <1% power distortion. OCIS codes: (060.4510) Optical communications; (060.4080) Modulation; (320.5540) Pulse shaping.
