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]. 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 …

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.

The blind demodulator’s performance in AWGN and a perfect channel is evaluated where it improves using a greater number OFDMA Downlink (DL) symbols and increased Cyclic Prefix (CP) length. Performance in a channel with a single multi-path interferer is also evaluated where the blind demodulator’s performance is degraded. chips away telephone number
