SCMA Codebook Design Based on a 16 Star-QAM with MED Maximization
نویسندگان
چکیده
The SCMA codebook design is based on star-QAM signalling constellations with operating several segmentations to generate the different user’s while considering MED maximization as criterion design. In addition, we constructed mapping matrix F using Progressive Edge Growth (PEG) algorithm which facilitate iterative decoding performance of message passing (MPA). At end, a comparison similar studies conducted MEDs designed codebooks.

SCMA with Low Complexity Symmetric Codebook Design for Visible Light Communication
Abstract—Sparse code multiple access (SCMA) is attracting significant research interests currently, which is considered as a promising multiple access technique for 5G systems. It serves as a good candidate for the future communication network with massive nodes due to its capability of handling user overloading. Introducing SCMA to visible light communication (VLC) can provide another opportun...
متن کامل16 QAM Communication with 1-Bit Transmitters
We present a novel non-linear precoding technique for the transmission of 16 quadrature amplitude modulation (QAM) symbols in a 1-bit massive multi-user (MU) multipleinput-single-output (MISO) downlink system. We deploy low resolution digital-to-analog converters (DACs) at the transmitter for the sake of decreasing the high energy consumption related to the massive MISO system. To mitigate the ...
متن کاملNonlinear impairment compensation using expectation maximization for dispersion managed and unmanaged PDM 16-QAM transmission.
In this paper, we show numerically and experimentally that expectation maximization (EM) algorithm is a powerful tool in combating system impairments such as fibre nonlinearities, inphase and quadrature (I/Q) modulator imperfections and laser linewidth. The EM algorithm is an iterative algorithm that can be used to compensate for the impairments which have an imprint on a signal constellation, ...
متن کاملSatellite Based Turbo-Coded, Blind-Equalized 4-QAM and 16-QAM Digital Video Broadcasting
The Pan-European Digital Satellite Video Broadcasting (DVB-S) system’s performance is characterized and improved with the aid of turbo coding and multi-level modulation. Specifically, various configurations of blind equalizers and convolutional as well as turbo codecs operating at different code rates were investigated. The standard system’s performance was improved upon replacing the conventio...
متن کاملCodebook Design of Keyblock Based Image Retrieval
This paper presents an image retrieval method based on keyblocks combing with interest points, furthermore the generation of codebook is also utilized to enhance the retrieval performance, where the balance between the retrieved precision and time cost can decide the codebook size of this CBIR system. Finally, the proposed method is compared with the method that only depends on interest points ...
