What are the essential characteristics of a broadband adaptive DFT Beam former .
1.In DFT beam former the weight vectors are changing per every frequency bin. But shouldn't the weight vector remain constant ?
2.how to prepare the data and convert the band pas signal to low pass signal ?
thank u for ur response
i finally did it with the help of Fm modulation...i think LFm will do also fine
here is what i have done have
T=2e-6;
Fs=440e6;
Fc=120e6;
B=200e6;
ft=0:1/Fs:T-1/Fs;
N=length(ft);
k=(Fc/Fs)*2*pi/max(ft);
y=modulate(ft,Fc,Fs,'fm',k); %%band pass...
well i tried this:
i need a broad band signal of band 500-1000 Hz
what i did is ...wrote code for above
and taken the idft....
and finally find fft to check ...but i am getting this
my code is :
clc;
close all;
clear all;
t=0:0.5:1000;
for i=1:length(t)
if i>=500 & i<=1000...
well ,I am about to design a broadband beam former. so I am curious,is it possible to create broadband signal of continuous frequency for a particular bandwidth. If no ,what is the best way to do so ?
