hello in my last studies project i have some problems;i'm working about study and simulation of a ds cdma system with urban multipath channel, the first problem that i need the publication of kozono and sieno about the urban channel ,i don't find it. then, i dont't know why we call it an urban channel ? ( technical view point). also in the simulation party, i've written the program but the problem that the simulated BER is very far from the theorical bcsause i want to achieve the results found by a scientist from the usa. i'm working about the synchronous and the asynchronous systems. the ber found in my simulation have a pics and breaks; someone has given me an advice to continue and stabilize this a matlab functions like SMOOTH, BERFIT... i have an amelioration but it stay far from the theorical. please help me
