Nothing to show WebThe process of demodulating an unknown wireless communication signal without knowledge of the channel state and modulation type is called the dual-blind demodulation problem. We focus on solving the dual-blind demodulation problem in the presence of multipath fading and noise. Traditional blind receivers have different functional blocks to …

WebBlind Demodulation 239 3 Blind Demodulation Framework An overview of the proposed blind demodulation framework is illustrated in Fig. 2. In the following, a brief description of the particular stages is provided. 3.1 Carrier Detection The detection of carriers is performed in the frequency domain using a well-averaged periodogram [6]. WebJun 19, 2024 · The estimation results of DPN along with its blind decoding performance are shown to outperform a blind signal processing algorithm for BPSK and QPSK on a simulated dataset. An over-the-air software-defined-radio capture was used to verify DPN results at high SNRs. DPN design can process variable length inputs and is shown to …
Webthe blind demodulation problem under generative prior we study is: find h 2 Rn and m 2 Rp, up to the scaling ambiguity, such that y 0 = G (1)(h)G(2)(m). In recent years, advances in generative modeling of images [Karras et al., 2024] has significantly increased the scope of using a generative model as a prior in inverse problems. Generative ... WebFeb 13, 2024 · In this framework, we accomplish sparse recovery and blind demodulation simultaneously by minimizing the induced atomic norm, which in this problem …
WebThe blind demodulator first rough-demodulates a signal with a period T to obtain a quasi-baseband signal x (t), and it becomes a discrete sequence x (mTs) (T after a fixed clock sample with a local period Ts and T satisfy the Nyquist basic sampling law, and generally use four times the sampling, that is, Ts=1/4T. WebMay 29, 2024 · Abstract: In digital communications, the accurate estimation of symbol rate is extremely important for both blind demodulation of non-cooperative communications and radio spectrum monitoring. An instantaneous frequency symbol rate estimation method is proposed in this paper for the QPSK signals. The method determines the symbol rate of …
