## Need help to write code in MATLAB for CHIRP SLOPE KEYING MODULATION

Dear sir/madam, I am working in implementation of chirp slope keying modulation and demodulation in matlab. Simulations that I completed are: 1. chirp signal(up and down chirp) generation completed 2. Linear frequency modulation/chirp signal simulated 3. Random data (...)

## Digital modulation technique - CSK

Hi all friends.I hope someone can help me about chirp slope keying modulation( CSK) technique in underwater communications.I am working on CSK and need to simulate in matlab. Please is there anybody here to give me ebook or something else.(maybe documents..)about chirp SLOPE KEYING MODULATION scheme for matlab). I will be (...)

## Need MATLAB code for CHIRP SLOPE KEYING MODULATION

## Generate Chirp signal in MATLAB

Hi guys, I would like to know, how to generate chirp signal delayed at n, n+1, n+2 relative to the 1st signal. I know how to generate the signal using 'chirp' function but how to make it delayed at a certain samples? Thanks in advanced.

## check for multipath effect in received signal

i am using a chirp signal of 17 to 19KHz sent from a phone to another. i want to know on the receiver side, if there is a multipath effect. How can i check that on matlab?

## spectrum and signal for chirp signal

Hi, I have post this question to matlab but no one answer :(. Hope someone help me in here. I have tried to plot the chirp signal from 20MHz to 70MHz in time domain and frequency domain. The target time and sweep time is set to 3 ms. Normally I see slew rate =1s, dont know why?. Sampling time = 140 us and samples per frame = 4096. The output of c

## how to generate a broadband signal for a given bandwidth in Matlab ?

If there should not be any signal parameters manipulaton, just continuous wave, then use chirp - linear FM. - - - Updated - - - If there should not be any signal parameters manipulaton, just continuous wave, then use chirp - linear FM.

## need to generate chirp signal

How could i generate upchirp and downchirp without using inbuilt function "chirp" in matlab ? i want to write a code for this. could any one tell me how to do this ?

## Help needed with xcorr in matlab

what are the parametrs of chirp

## CST excitation With chirp signal

Hi I am trying to excite CST with chirp signal. Is there any one explain me how can I import my matlab chirp file into CST as an excitation signal. thanks a lot

## chirp signal with Matlab

help chirp chirp Swept-frequency cosine generator. Y = chirp(T,F0,T1,F1) generates samples of a linear swept-frequency signal at the time instances defined in array T. The instantaneous frequency at time 0 is F0 Hertz. The instantaneous frequency F1 is achieved at time T1. By default, F0=0, T1=1, and F1=100. (...)

## Corrrelation to extract harmonics from a signal!

Hi I need to extract the 2nd harmonic from a waveform. I think I need to use correlation but I have no idea where to start. Can anyone provide some matlab help. The experiment is to fire a chirp signal at a bubble and measure the response from the bubble to see if it resonates. I have a hydrophone to collect the received data. I've got the da

## Chirp Spread Spectrum Algorithm + Matlab

Where can I find any information regarding chirp spread spectrum algorithm? Is there any book/notes that i can read on improving my knowledge on chirp spread spectrum? Thanks in advance, Allyson

## Bandpass filter with chirp signal input

I am trying to emulate the output from a Gammatone filter for a hyperbolic chirp as input. The matlab script is shown below. I have generated a hyperbolic chirp with frequency sweeping from 100kHz to 20kHz in 1ms. And the Gamma tone filter has center frequency of 50kHz and bandwidth of 20kHz. This means, theoretically the filter output (...)

## how to plot a filter whose input is a chirp signal ?

Hi all i have a data file which is the op of a filter whose input is a chirp signal these are 16 bit samples now i need to import this data file into matlab or scilab as an object and plot it to get the filter response.How do i do it??? thanks in advance regards srinivas

## Chirp generator in VHDL

I would use a DDS. Here is a description of the general technique, however it doesn't give VHDL details: "Generate Digital chirp Signals With DDS" by Bar-Giora Goldberg

## Help me with mixing the Tx and Rx signal then LPF in Matlab

Hi, Iam trying to do some analysis for a redar system that uses Linear chirp modulation. I have a problem mixing the Tx and Rx signal then LPF. RX is a delayed version of the Tx. Normally after mixing (muliplying Tx and Rx) i dont get the low freq part!!! I tried matlab Help but i cannot get it! Any help Please? Ho

## Help me writing a Matlab code for analyzing chirp signal

Why dont you use the matlab help? It pretty simple I think. Generate the chirp signal then take its FFT and then plot it t = 0:0.001:2; % 2 secs @ 1kHz sample rate y = chirp(t,0,1,150); f=fft(y); plot(f)

## Question about up and down chirp signal and its dft

i want code for simple up and down chirp signals and i had tried it from the matlab my doubt iis that what we can infer from the dft of chirp signal and how can we know chirp rate from dft also how to differentiate upand down chirp from fft plz help this is main part of my project so plz do help thanks in (...)

## How to generate up chirp and down chirp signal in Matlab?

Search your matlab installation directory for file chirp.m. It contains the source code of the chirp function.
