Modified SNR Gap Approximation for Resource Allocation in LDPC-Coded Multicarrier Systems
IEEE Access, 2020 The signal-to-noise ratio (SNR) gap approximation provides a closed-form expression for the SNR required for a coded modulation system to achieve a given target error performance for a given constellation size. This approximation has been widely used for

Adaptive redundant residue number system coded multicarrier modulation
, 2000 The novel class of nonbinary maximum minimum distance redundant residue number system (RRNS) codes is invoked in the context of adaptively RRNS coded, symbol-by-symbol adaptive multicarrier modulation, in order to combat the effects of frequency ...

EURASIP Journal on Wireless Communications and Networking, 2004 Multiple-access interference and interfinger interference limit the capacity of conventional single-carrier DS-CDMA systems. Even though multicarrier CDMA posses the advantages of conventional CDMA and OFDM, it suffers from two major implementation ...

Large-Scale Multicast Group Secure Transmission Scheme Based on Multi-Carrier FDA
Sensors, 2023 Aiming at the problem that the traditional physical layer technology cannot realize secure transmission due to the large number of users and wide dispersion in the multicast system, a layered transmission method is proposed, and a scheme for the secure ...

Advanced Materials Interfaces, Volume 13, Issue 6, 16 March 2026.Mixed halide perovskites suffer from photo‐induced phase segregation, leading to compositional instability and degraded device performance. This review summarizes the dynamic behavior and kinetics of phase segregation in thin films under external stimuli, analyzes compositional and environmental effects, and proposes suppression strategies to enhance ...
