  • Method for optimizing spectral re-use
    Patent number: 6085094
    Abstract: A method for optimizing spectral re-use between an interferer digital phase modulated cellular system and a desirable analog phase modulated cellular system is disclosed wherein an optimal guard band to use with adjacent channel interference is determined, or an optimal guard zone to use with co-channel interference is determined. This is achieved by determining the effect of interference due to a digital phase modulated signal at the baseband of a desired analog phase modulated signal. By the use of this invention, the capacity of a desired system and/or the quality of a service provided by a desired system may be enhanced.
