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

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.)?
