LDPC Codes in Communications and Broadcasting
Low-density parity-check (LDPC) codes are one of the most powerful error correcting codes and are attracting much attention these days. LDPC codes are promising for communications and broadcasting as well where the use of error correcting codes are essential. LDPC codes have been standardized in some communication standards, such as, IEEE802.16e, DVB-S2, IEEE802.3an (10BASE-T), and so on. The p...
متن کاملTurbo and LDPC Codes for Digital Video Broadcasting
The Digital Video Broadcasting (DVB) Project was founded in 1993 by the European Telecommunications Standards Institute (ETSI) with the goal of standardizing digital television services. Its initial standard for satellite delivery of digital television, dubbed DVB-S, used a concatenation of an outer (204,188) byte shortened Reed Solomon code and an inner constraint length 7, variable rate (r ra...
متن کاملAdvanced Decoding Algorithms for Satellite Broadcasting
This paper presents an iterative decoding algorithm for concatenated codes consisting of a Reed-Solomon and a convolutional code, focusing on the code of the DVB-S standard. Existing solutions for the different decoding stages and their interfaces are discussed and their performance is compared. Besides, a new procedure is proposed to define the feedback signal from the output of the Reed-Solom...
متن کاملMultilevel LDPC Codes Design for Multimedia Communication CDMA System
We design multilevel coding (MLC) with a semi-bit interleaved coded modulation (BICM) scheme based on low density parity check (LDPC) codes. Different from the traditional designs, we joined the MLC and BICM together by using the Gray mapping, which is suitable to transmit the data over several equivalent channels with different code rates. To perform well at signal-to-noise ratio (SNR) to be v...
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...
