Separable Codes for the Symmetric Multiple-Access Channel

Polar Codes for the -User Multiple Access Channel

——In this paper, polar codes for the -user multiple access channel (MAC)with binary inputs are constructed. It is shown that Arikan’’s polarization technique applied individually to each user transforms independent uses of an -user binary input MAC into successive uses of extremal MACs. This transformation has a number of desirable properties: 1) the ““uniform sum-rate”” of the original MAC is ...

Linear codes for the sum mod-2 multiple-access channel with restricted access

‏‎facilitating lexical access for the fluent production of speech‎‏

‏‎the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis , a one- way anova experimental design was carried out. 24 senior student of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inte...

LDPC Codes over Gaussian Multiple Access Wiretap Channel

Abstract: We study the problem of two-user Gaussian multiple access channel (GMAC) in the presence of an external eavesdropper. In this problem, an eavesdropper receives a signal with a lower signal-to-noise ratio (SNR) compared to the legitimate receiver and all transmitted messages should be kept confidential against the eavesdropper. For this purpose, we propose a secure coding scheme on thi...
