The IDFT can be implemented via a computationally efficient FFT algorithm. The orthogonality of subcarriers in OFDM can be maintained and individual subcarriers can be completely separated and demodulated by an FFT at the receiver when there is no ISI introduced by communication channel. In practice...
Based on the orthogonality between subcarriers in the fast Fourier transform (FFT) property, the proposed algorithm attempts to minimize the sum-squared correlation (SSCM) between each sample located in a well-defined window to update the CSE coefficients. Thus, the combined channel-CSE response ...
1. Formal proof complexity models for QCDCL using arbitrary decisions.We provide a formal proof-complexity model for QCDCL with arbitrary decisions. This follows a recent line of research to formalise and rigorously analyse QCDCL from a proof complexity perspective [5,9]. Our most general modela...
