Digital Signal Processing (DSP) is the manipulation of real-world signals within a digital computer, using mathematical techniques to enhance, change, or display the data in a specific way. It involves converting analog signals (such as audio or video) into digital form and performing various ope...
Fig. 2 shows the power hash diagram when the number of observed signals is m=3. It can be seen from the figure that the power points of the observed signals also exhibit linear clustering characteristics in space. When the number of observed signals m>3, the power scatter plot cannot be...
The principle block diagram of CAE is shown in Fig. 4. (1) Convolution layer convolution: Assuming that there are k convolution kernels in CAE, each convolution kernel consists of parameters ωk and bk , firstly initialize k Fig. 4 CAE principle block diagram Wu et al. ...

Table 1. The phases of the frequency modulation signals. The binary phase shift keying signal (BPSK) and Frank-coded polyphase signal (Frank) are the phase-modulated radar signals, whose phases are shown in Table 2. In the table, 𝜃∈{0,𝜋}θ∈{0,π} indicates the initial phase, ...
Describing signal characteristics solely using a specific domain or feature space is insufficient to achieve accurate recognition. Therefore, in terms of feature engineering, this paper proposes combining multiple domain features to construct a composite feature space for representing signal characteristics. ...
FIG. 2 is a diagram of assistance in explaining a basic configuration (first example) of the reference signal transmission system; FIG. 3 is a diagram of assistance in explaining a basic configuration (second example) of the reference signal transmission system; FIG. 4 is a diagram of assistan...
Instead of well separated independent gates, both, control gate as well as polarity gate, couple to the whole channel region. This is achieved by a thin planar channel, having a front and backgate both covering the whole channel. Naturally, this design consumes less space to be brought onto...
This article presents signal processing algorithms used as a new remote sensing tool, that is passive bistatic SAR with navigation satellites (e.g. GPS, GLONASS or Galileo) as transmitters of opportunity. Signal synchronisation and image formation algorithms are described for two system variants: one...
Simulate BPSK transceiver Note, this is not the CDMA waveform, just for testing/understanding how to send/receive phase modulated signals: ~/rpgr PSK_sim.grc Actual BPSK transceiver with Red Pitaya This saves the received packets to a file. They should match the transmitted packets. Again, thi...
