Hello everybody!!!
i m studying on my my thesis and there re some points that slow me down:(( i urgently need your help!!!

Firstly,on a rake receiver structure how a search finger detects the time delays?Should i use a crosscorrelation on matlab,and how?
i ve read many books for wcdma and rake rec. but i havent found an answer to that:((
When a delayed signal arrives to rake,what is done to combine all signals(i ve seen that it s used MRC to combine them)but i dont know hot to implement it on matlab?
I ve seen some wcdma rake codes but unfortunately i havent understood them at all...if s.o may help me about the steps that i should take,i ll be really grateful...
