Low Complexity Joint Channel Estimation and Data Detection for AFDM Receivers With Oversampling
Kuranage Roche Rayan Ranasinghe, Yao Ge, Giuseppe Thadeu Freitas de Abreu +1
In this paper, we propose a novel low complexity time domain (TD) oversampling receiver framework under affine frequency division multiplexing (AFDM) waveforms for joint channel es…

Generalized Arlery-Tan-Rabaste-Levenshtein Lower Bounds on Ambiguity Function and Their Asymptotic Achievability
Lingsheng Meng, Yong Liang Guan, Yao Ge +2
This paper presents generalized Arlery-Tan-Rabaste-Levenshtein lower bounds on the maximum aperiodic ambiguity function (AF) magnitude of unimodular sequences under certain delay-D…
