Guard band allocation and spectral efficiency

  1. Aug 9, 2011 #1
    I am wondering what factors go into spectral efficiency and determining and calculating guard bands. Could a tunable antenna or filter within a handset reduce the necessary size of a guard band thereby increasing a networks spectral efficiency? How are guard bands determined/defined and by who (govermentally allocated or is it left with the networks to determine. Any information (articles/references/ empirical data w/e) you have on guard bands and increasing spectral efficiency with impedance matching components would be very helpful!
