I an doing my project on implementation of n ratio logic based cooperative sensing using double threshold energy detection . can anyone please send me the matlab code for this or for simple single energy detection implementation (so as to get my roots strong)........ > > > > Sure, would you like someone to do your project for you too? Im afraid that you will find that is not how this board works. Nobody is just going to send you code. Ask detailed questions about what you have tried and where you are stuck, post the code that you have tried to give better ideas of the problems you are facing. The ultimate goal is that you learn how to solve your problems yourself. There is a file exchange on this website if you want to see if someone has posted code similar to what you are looking for but be forewarned anyone can post there and the accuracy of the code is not verified by anyone so do not assume that it will work for your intended purpose. It is amost always better to write your own code since. hi there, i am doing a project on collaborative on energy detection in collaborative spectrum sensing in cognitive radio and i have done simulation for independent log normal shadowing and rayleigh fading but in collaborative spectrum sensing rayleigh fading simulation is done but spatially correlated log normal shadowing i dont understand how to do it. The formula that i have used in my silmulation for independent log normal shadowing is σ=0.1log(10) σ2 but with in collaboarive spectrum sensing the correaltion function R(d)=e^-ad comes in spatially correlated log normal shadowing with a being constant with different values for urband and suburban value and d bieng the distance b/w users but i dont know how do the simulation where should the correlation function comes pls can anyone help i my code i have use chi square distribution for probability of false alarm and non central chi square di for prob of detection.
