    Hi i am a Masters student in USA ... i am working on my thesis which is on computing Guard band for Interference ... i am unable to find the exact relationship between the guard band and Interference


    Lets say interference is some X db between two channels which are transmitting simultaneously then for that X amount of Interference what should be the guard band spectrum to be assigned ... I am looking for the exact formula ...

    say like GB = Interference * some relation

    Please help me .... its urgent

    Doesn't seem that urgent to me.

    Wouldn't guard band width depend entirely on adjacent signal falloff, and also require an interference ceiling (eg. max -60dB interference; -80dB/dec falloff)? What do you have so far? Did you assume a characteristic distribution for the signals (eg. Gaussian, Hamming, etc.)?
