PEmORMANCE ANALYSIS OF A PRE-FFT EQUALIZER DESIGN FOR DVB-T
Conventional OFDM employs a guard interval to combat delay spread distortion oftransmitted data. This reduces the efliciency of the OFDM transmission. The combined OFDM-Equalization strategy described here employs an Adaptive Equalizer to combat delay spread distortion and thereby facilitates the use of very short guard intervals and thus a more eflcient OFDM modulation scheme. The OFDM receive...
متن کاملProposed Pilot Pattern Methods for Improvement DVB-T System Performance
Recently, orthogonal frequency division multiplexing (OFDM) has been extensively used in communications systems to resist channel impairments in frequency selective channels. OFDM is a multicarrier transmission technology in wireless environment that use a large number of orthogonal subcarriers to transmit information. OFDM is one of the most important blocks in digital video broadcast-terrestr...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Using WPT as a New Method Instead of FFT for Improving the Performance of OFDM Modulation
Orthogonal frequency division multiplexing (OFDM) is used in order to provide immunity against very hostile multipath channels in many modern communication systems.. The OFDM technique divides the total available frequency bandwidth into several narrow bands. In conventional OFDM, FFT algorithm is used to provide orthogonal subcarriers. Intersymbol interference (ISI) and intercarrier interferen...
