    Looking for Matlab simulations of MIMO for CDMA

    Re: mimo code no help :( .....cant believe nobody has done cdma in mimo.....i dont have time otherwise i would have done it myself....i just need graphs...i tried looking it on mathworks too but couldnt find it there is there anyone who could help?

    Looking for CDMA related simulations in Matlab

    hi guys i need simulation in matlab for cdma...ds-cdma and mc-cdma..all sort of simulations related to them...like BER plots,performance in fading channels, AWGN channel and in different issues..do you know where i can find them or if anyone has got them, could you please kindly upload them

    orthogonal frequencies

    so you mean to say they wont add up or subtract with each other like the other signals do?

    orthogonal frequencies

    hi can anyone explain why dont orthognal frequencies interfere they say in ofdm frequencies are orthognal so they dont interfere but i dont get it how does it happen

    Help me understand this equation made using KCL

    hey guys below is the circuit given for node analysis. now using kcl we come up with following equations GAE1 + G3(E1 - E2) = I1 (1) GBE2 - G3(E1 - E2) = I2 (2) i used plus in equation 2 before G3(E1 - E2) but my friend told me that it should be negative.i am too...

    How to write cos squared of angle phi ?

    Re: syntax problem yeah now i figured out the other problem i was squaring array with ^2 instead of .^2 thank you guys for your help in correcting my syntax cos(phi)^2 was the correct way of doing it have hit 'helped me' tab for all of you Added after 6 minutes: actually that x was an...

    How to write cos squared of angle phi ?

    hey guys i have some syntax problem in this statement d=sqrt((x(1:length(x))-r*sin(phi))^2 + r^2 *cos^2(phi)) it gives me error on cos^2(phi)...can anyone tell me how to write cos squared of angle phi

    an insightful explanation required

    thanks kral this is exactly the kind of explanation i was looking for...thanks alot

    an insightful explanation required

    well yeah you are right..we have been told that capacitor conducts ac completely and inductor blocks it this concept seems to work fine in parallel resonant LC circuits...but it just cant explain the series LC circuit kuz in parallel when ac is applied across both of them, caparcitor charges and...
