1. ### Why OMP is iterative? Can we find the support in one step?

In OMP why the 'support' of the received signal is not found in one step, by selecting the \$K\$ maximum correlated columns of the sensing matrix \$A\$? where \$K\$ is the sparsity of the signal. Like in MATLAB [val ind] = sort(A'*Y); %Y is received signal signal_Support = ind(1:K)...
2. ### How to compute the location of the antenna when I rotate it?

Hi group, I have a question regarding to detect the location of the antenna. I read this link: https://en.wikipedia.org/wiki/Plane_wave In the "Complex exponential form" part, the equation: U(r,t) = U0 * exp(j*(k.r - w*t) as the function of location and time U0 = A0 * exp(j*phi) : A0 and...
3. ### How to calculate standard deviation from the delay?

I am trying to calculate the unit vector and standard deviation of the signal. I hope everyone can give me ideas. Here is my scenario: I have 2 rx channels: - f is channel 1 with the length 1x256 complex, then FFT. - g is channel 2 with the length 1x256 complex, then FFT. - from f and g, I can...
4. ### How to detect multipath?

Hi everyone, I am a new engineer just work in the real industry, so I would like to collect more experience from the real project. I am working on the Multipath problem, but I've not done before in the University, and really do not know how to solve it. During the discussion from the...
5. ### Very tricky Solar-Module Disconnecting Problem

My non-ee boss gave me a design assignment I'm not sure is physically possible. I work at a solar panel manufacturing company. He wants me to essentially add a device to the mc4 connectors between modules which would allow disconnecting each module in a string from one another. He wants this...
6. ### Frame Synchronisation via Modified Approach to Bit Insertion

Homework Statement I am currently embarking on a project which requires me to design a system where I can transmit voice over a distance, by inputting an analog voice signal on one end and then recovering the voice which I input on the transmitting end at the receiving end. The general design...
7. ### Equation of SNR versus sigma square for BPSK

I would like to know in the following equation (attached) how can I incorporate BER for BPSK? is BER the same as Rc? The equation is relation between SNR and sigma square.
