Patent ID: 8331281

Claim:
A computer program product comprising a non-transitory computer-readable medium having computer program code executable by a processor, where the computer program code includes: first computer readable program code that enables a processor to account for a desired carrier to noise spectral density for a communication link of interest (φ m,ni ) and a noise factor in the transponder (θ m,ni ) based on the desired carrier to noise spectral density (φ m,ni ); second computer readable program code that enables a processor to adjust a spectral overlap of a plurality of communication links (Δ m,nk ) for uplink path gains from a plurality of communication beams (a m,n,ni and a m,n,kj ); third computer readable program code that enables a processor to apply reduced dimension spectral overlap values (δ m,nk ), based on the adjusted spectral overlap values (ρ m,k,kj ) of the plurality of communication beams, to an expression that defines a transponder input (x m,ni ) for a communication beam of interest (n); fourth computer readable program code that enables a processor to compute the transponder input power (x m,ni ) for the communication link of interest (i) using a composite power computation (x m,n ); and wherein i and j represent communication link indices, k and n represent communication beam indices, n indicates a communication beam of interest, and m indicates a plurality of communication beams that do not include the communication beam of interest.
