    how to add paths of a multipath signal ?

    i have used a simulator for generating a signal where the signal arrived at different paths each with different mag. and phase how to add these paths considering they came at different delays i have found this equation but dunno how to implement it in matlab

    Matlab _micro serial connection

    yes if you are saving the received bytes in an vector say ( A ) for i =1:100 A(i) = fread(serialObject, 1); end ,,, then you can save by using save myData.mat A ,,, when you like to load it load myData.mat

    [SOLVED] help me making RF receiver circuit ,,,

    really thanks that's very helpful i'm making jamming locator device it's basic idea depends on receiving signal from array antenna and perform some operation on the signal so i need an antenna first to accept the signal then pass to rf receiver consists of mixer,oscillator and amplifier...

    [SOLVED] help me making RF receiver circuit ,,,

    i want to make 2.4 gh receiver ,,, i really don't know what to do is there is away that i could change the circuit of router to a receiver or is there is circuit ,,, or should i decrease the freq is so to which freq

    help me in my graduation project ( jammer locator )

    so ? is it hard ... i just begin reading some book .. some on linear algebra ( eigenvalue and eigenvectors ) and estimation of angle of arrival ,, dunno should i continue or not

    help me in my graduation project ( jammer locator )

    any help ???? - - - Updated - - - now i considering working on 433 mhz or 2.4 gigha hz ,,,, and the detection type i will use angle of arrival so how could i measure the phase difference if i receiving on two antenna's

    help me in my graduation project ( jammer locator )

    i think it must be good enough , so what tool should i use - - - Updated - - - yeah but i just build a concept device ,,, and if it's spread i think the jammer will impact the whole wide band .

    help me in my graduation project ( jammer locator )

    hi guys i working on a project based on finding a jammer at a certian freq i'm new at that field so while searching on the internet i find there are several ways for discovery of the position can be realized utilizing range measurements including received signal strength, time of arrival, time...

    interfacing pc to pic using RS485 (help me)

    sorry i can't understand you ... here in rs485 there are many slaves and one master ... the master while sending specify the direction of data by typing the address of slave he want to send to him like if i have 5 slaves ... 161 162 163 164 165 ... i want to send to third one only i...
