Rate-Splitting Multiple Access (RSMA) has emerged as a flexible and powerful framework for wireless networks. In this paper, we investigate the user fairness of downlink multi-antenna RSMA in short-packet communications with/without cooperative (user-relaying) transmission. We design optimal time allocation linear precoders that maximize Max-Min Fairness (MMF) rate with Finite Blocklength (FBL)...
Quantum Cryptography has demonstrated the potential for ultra-secure communications. However, with quantumchannel transmission rates in the MHz range, typical link losses and signal-to-noise ratios have resulted in keyproduction rates that are impractical for continuous one-time-pad encryption of high-bandwidth communications. We have developed high-speed data handling electronics that support ...
A classic example of ecophysiological adaptation is the observation that animals from hot arid environments have lower basal metabolic rates (BMRs, ml O2min-1) than those from non-arid (luxuriant) ones. However, the term 'arid' conceals within it a multitude of characteristics including extreme ambient temperatures (Ta, degrees C) and low annual net primary productivities (NPPs, gCm-2), both of...
T his study investigates the short-run and long-run impact of real exchange rate misalignment and volatility on Indonesian export to the US by exploiting the disaggregated data of export volume. The proxy of real exchange rate misalignment was obtained by estimating the fundamental equilibrium exchange rate (FEER) model, and the exchange rate volatility measured by employing the GARC...
vocabulary as a major component of language learning has been the object of numerous studies each of which has its own contribution to the field. finding the best way of learning the words deeply and extensively is the common objective of most of those studies. however, one effective way for achieving this goal is somehow neglected in the field. using a variety of activities such as games can r...
Code-excited linear prediction (CELP) is the predominant methodology for communications quality speech coding below 8 kbps, and several variable-rate CELP schemes have been discussed in the literature, including QCELP, the variable-rate wideband digital cellular mobile radio speech coding standard specified in IS-95. A key component of these speech coders is the detection and classification of ...
