Homework Statement I want to generate a Ricean channel using MATLAB Homework Equations Assuming that Ω = -30 dB. The Attempt at a Solution I know how to generate a Rayleigh channel using matlab: H = 1/sqrt(2) * ( randn(N,M) + j*randn(N,M) ) But I really have no idea how to do that for...

Hi everyone, I'm trying to simulate an OFDM following a few steps, and I'm stuck at the first: The first step: You have a channel with independent zero mean complex Gaussian taps along with exponentially decaying power profile E{|hk|2|}=e-k/3 with k ∈ [0,21] First of all, does this notation...

Thank you for your quick respond. My question is whether this approach OK or not. And if the feedback resistance can be reduced more.

Homework Statement Reduce the feedback resistance for the following T-Network Homework Equations Basic circuit analysis (Thevenin maybe?) The Attempt at a Solution My first though was to use Thevenin, and actually I've found some book used that method:

Thanks. I really appreciate your help. :)

Sorry for the "typo" ^^" Anyway, this is what I've done: http://s32.postimg.org/da0hvrf5h/004.jpg Am I doing OK?

Homework Statement If V(1)=10 V and V(0)=5 V, and the voltage threshold for all diodes is 0.6 V. Determine the current through every diode and the output voltage Vo if V1=V4= 5V and V2=V3=10 V. Homework Equations Basic KCL & KVL. The Attempt at a Solution I know that the basic idea to...

Homework Statement Find Io(s)/Ii(s) Homework Equations Basic KVL laws. The Attempt at a Solution My idea is to start from the RHS of the circuit until I get a relation between Io(s) and Ii(s). Actually I stopped at this point, I wondered whether my approach is appropriate or not since...

Homework Statement The first order ramp unit response is shown in the graph below. Determine: 1. The transfer function. 2. Plot the error function e(t) then determine its maximum magnitude and the time http://s24.postimg.org/cdbhqm80j/Capture.png Homework Equations G(s)=(1/T)/(S+1/T) ... G(s)...

Homework Statement A conducting square loop (L × L) moving with velocity vo ay m/s where the magnetic flux density is B=Bo ax Wb/m2 in 0 < y < 2L, and is equal to zero when 0 > y and y > L. Determine the current in the loop and plot its magnitude as a function in the loop's position in the...

That's the exact statement of the problem. I guess we have to assume that the tank is full of water, which means that the volume of water is 1 m3.

Homework Statement An Engine works within Otto cycle where the compression ratio is 6, and 350 kJ of heat was added to it. Determine the efficiency of the cycle and the work done if Cp/Cv is 1.45Homework Equations Efficiency Otto = (1- r1-k) Efficiency (eff.) =Work (W) /Heat Transferred (Q)The...

Homework Statement A tank has a saturated liquid at 0.2 MPa. An amount of heat is transferred until the pressure in the tank became 0.1 MPa. If the volume of the tank 1 m3. Determine: 1- The final state of the water 2- The mass of the vapor in the tank 3- The work 4- The process on P-v...

W3-4=852.44 kJ/kg Wnet=859.44 kj/kg W`net=2.5783e04 kj/s qboiler=2.901e03 eff. = Wnet/qboiler * 100 = 29.63%

Okay, my bad ^^", but the approach is correct, right?
