I am studing "Bajwa et al.: Compressed Channel Sensing: A New Approach to Estimating Sparse Multipath Channels." I want to make matlab code about CCS 3 in the paper.
--Matlab code--
N0 = 5; % code length
M = 1; % the num. of codes
L = 5; % maximum delay
N0tilda = N0 + L -1;
--explain--
X is an N0tilda X L(2M+1) block matrix of the form
X = [X_{-M} ..... X_{0} ..... X_{M}.
--Matlab code--
X = zeros(N0tilda,L*(2*M+1));
---------------------------------------------------
Question?
How can I code X = [X_{-M} ..... X_{0} ..... X_{M}?
Here, each block Xm has dimension N0tilda x L
--Matlab code--
Xm=zeros(N0tilda,L);
