Direction of Arrival (DoA) Online Simulator (using MUSIC)

Interactive DOA Simulator X-axis XY angle (deg): 45 XZ angle (deg): 30 Noise: 0.05 Y-axis XY angle (deg): 60 YZ angle (deg): 45 Noise: 0.05 Z-axis XZ angle (deg): 60 YZ angle (deg): 30 Noise: 0.05 Estimated DOA (deg): 0 Simulation Workflow and Mathematical Background This simulator demonstrates Direction of Arrival (DOA) estimation using three-axis sensor signals (X, Y, Z), Maximal Ratio Combining (MRC) , and the MUSIC algorithm . It allows interactive control of signal angles and noise for teaching purposes. 1. Signal Generation A pure sinewave signal of frequency f is projected onto three axes using user-defined angles in different planes: X-axis: ฮธ XY , ฮธ XZ Y-axis: ฮธ XY , ฮธ YZ Z-axis: ฮธ XZ , ฮธ YZ Mathematically, for each time sample t : x(t) = s(t) * cos(ฮธ_xy_x) * cos(ฮธ_xz_x) + n_x(t) y(t) = s(t) * sin(ฮธ_xy_y) * cos(ฮธ_yz_y) + n_y(t) z(t) = s(t) * sin(ฮธ_xz_z) * sin(ฮธ_yz_z) + n_z(t) wh...

Constellation Diagrams of ASK, PSK, and FSK (with MATLAB Code + Simulator)

Constellation Diagrams: ASK, FSK, and PSK Comprehensive guide to signal space representation, including interactive simulators and MATLAB implementations. ๐Ÿ“˜ Overview ๐Ÿงฎ Simulator ⚖️ Theory ๐Ÿ“ˆ Q-function ๐Ÿ“š Resources BASK Modulation Transmits one of two signals: 0 or $\sqrt{E_b}$, representing binary 0 and 1. Simple but sensitive to noise. BFSK Modulation Transmits one of two signals: $\sqrt{E_b}$ on the Y-axis or $\sqrt{E_b}$ on the X-axis. These are orthogonal signals. BPSK Modulation Transmits $+\sqrt{E_b}$ or $-\sqrt{E_b}$ (antipodal signaling). Most efficient binary scheme. ...

DSB-SC Modulation and Demodulation

๐Ÿ“˜ Overview ๐Ÿงฎ DSB-SC Modulator ๐Ÿงฎ DSB-SC Detector ๐Ÿงฎ Comparisons ๐Ÿงฎ Q & A Summary ๐Ÿ“š Further Reading Double-sideband suppressed-carrier transmission (DSB-SC) is transmission in which frequencies produced by amplitude modulation (AM) are symmetrically spaced above and below the carrier frequency and the carrier level is reduced to the lowest practical level, ideally being completely suppressed. In the DSB-SC modulation, unlike in AM, the wave carrier is not transmitted; thus, much of the power is distributed between the sidebands, which implies an increase of the cover in DSB-SC, compared to AM, for the same power use. DSB-SC transmission is a special case of double-sideband reduced carrier transmission. It is used for radio data systems. This model is frequently used in Amateur radio voice communications, especially on High-Frequency bands. Spectrum DSB-SC i...

FM Modulation Online Simulator

Frequency Modulation (FM) Simulator In Frequency Modulation, the frequency of the carrier signal varies in accordance with the message signal's amplitude. See Mathematical Background=> Change the parameter values to see the effect. Message Frequency (fm): Hz Carrier Frequency (fc): Hz Carrier Amplitude (Ac): Modulation Index (ฮฒ): Frequency deviation ฮ”f = ฮฒ × fm s FM (t) = A c cos(ฯ‰ c t + k f ∫m(t)dt) where ฯ‰ = 2ฯ€f & k f = Frequency Sensitivity Modulation index, ฮฒ = (k f * A m ) / f m FM Modulation & Demodulation Online Simulator → ๐Ÿงช Experiment for Students: "Changing carrier amplitude affects only the displayed signal magnitude and transmitted power. It does not change the frequency deviation, modulation index, or bandwidth of an ideal FM signal. In another simulator , set the Message Amp...
