Channel Impulse Response (CIR)

๐Ÿ“˜ Overview & Theory ๐Ÿ“˜ How CIR Affects the Signal ๐Ÿงฎ Online Channel Impulse Response Simulator ๐Ÿงฎ MATLAB Codes ๐Ÿ“š Further Reading What is the Channel Impulse Response (CIR)? The Channel Impulse Response (CIR) is a concept primarily used in the field of telecommunications and signal processing. It provides information about how a communication channel responds to an impulse signal. It describes the behavior of a communication channel in response to an impulse signal. In signal processing, an impulse signal has zero amplitude at all other times and amplitude ∞ at time 0 for the signal. Using a Dirac Delta function, we can approximate this. Fig: Dirac Delta Function The result of this calculation is that all frequencies are responded to equally by ฮด(t) . This is crucial since we never know which frequenci...

Power Spectral Density Calculation Using FFT in MATLAB

๐Ÿ“˜ Overview ๐Ÿงฎ Steps to calculate the PSD of a signal ๐Ÿงฎ MATLAB Codes ๐Ÿ“š Further Reading Power spectral density (PSD) tells us how the power of a signal is distributed across different frequency components, whereas Fourier Magnitude gives you the amplitude (or strength) of each frequency component in the signal. Steps to calculate the PSD of a signal Firstly, calculate the first Fourier transform (FFT) of a signal Then, calculate the Fourier magnitude of the signal The power spectrum is the square of the Fourier magnitude To calculate power spectrum density (PSD), divide the power spectrum by the total number of samples and the frequency resolution. {Frequency resolution = (sampling frequency / total number of samples)} Sampling frequency (fs): The rate at which the continuous-time signal is sampled (in Hz). ...

Coherence Bandwidth and Coherence Time

๐Ÿงฎ Coherence Bandwidth ๐Ÿงฎ Coherence Time ๐Ÿงฎ MATLAB Code s ๐Ÿ“š Further Reading For Doppler Delay or Multi-path Delay Coherence time T coh ∝ 1 / v max (For slow fading, coherence time T coh is greater than the signaling interval.) Coherence bandwidth W coh ∝ 1 / ฯ„ max (For frequency-flat fading, coherence bandwidth W coh is greater than the signaling bandwidth.) Where: T coh = coherence time W coh = coherence bandwidth v max = maximum Doppler frequency (or maximum Doppler shift) ฯ„ max = maximum excess delay (maximum time delay spread) Notes: The notation v max −1 and ฯ„ max −1 indicate inverse proportionality. Doppler spread refers to the range of frequency shifts caused by relative motion, determining T coh . Delay spread (or multipath delay spread) determines W coh . Frequency-flat fading occurs when W coh is greater than the signaling bandwidth. Coherence Bandwidth Coherence bandwidth is...
