NEW COMPUTER GENERATED-SCMA CODEBOOK WITH MAXIMIZED EUCLIDIAN DISTANCE FOR 5G

open access: yesIraqi Journal of Information & Communication Technology, 2019
Sparse code multiple access (SCMA) is one of the Non-Orthogonal Multiple Access (NOMA) that attracts many researchers for its promising future uses in 5G systems. In this paper, a Computer Generated-Sparse Code Multiple Access (CG-SCMA) is proposed.

Carrier recovery techniques on satellite mobile channels [PDF]

open access: yes
An analytical method and a stored channel model were used to evaluate error performance of uncoded quadrature phase shift keying (QPSK) and M-ary phase shift keying (MPSK) trellis coded modulation (TCM) over shadowed satellite mobile channels in the ...

A co-designed equalization, modulation, and coding scheme [PDF]

open access: yes
The commercial impact and technical success of Trellis Coded Modulation seems to illustrate that, if Shannon's capacity is going to be neared, the modulation and coding of an analogue signal ought to be viewed as an integrated process.

Joint Multilevel Turbo Equalization and Continuous Phase Frequency Shift Keying

open access: yesEURASIP Journal on Wireless Communications and Networking, 2008
A novel type of turbo coded modulation scheme, called multilevel turbo coded-continuous phase frequency shift keying (MLTC-CPFSK), is designed to improve the overall bit error rate (BER) and bandwidth efficiency. Then, this scheme is combined with a new

Iterative channel equalization, channel decoding and source decoding

open access: yes, 2005
The performance of soft source decoding is evaluated over dispersive AWGN channels. By employing source codes having error-correcting capabilities, such as Reversible Variable-Length Codes (RVLCs) and Variable-Length Error-Correcting (VLEC) codes, the ...
