Wavelet-based multicarrier transmission over multipathwireless channels
Electronics Letters, 2000 The conventional Fourier-based complex exponential carriers of a multicarrier system are replaced with orthonormal wavelets in order to reduce the interference. The wavelets are derived from a multistage tree-structured Haar and Daubechies orthonormal quadrature mirror filter (QMF) bank.

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 ...

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 ...
