摘要：

Linearised amplifiers are generally designed with the goal of reducing two-tone intermodulation. In multicarrier systems the signal entering a broadband amplifier is quite different from this, being Gaussian distributed. The goal of optimising the S/I ratio produced with this kind of signal is usually rejected because of its complexity. A direct formula for S/I computation is obtained and used to optimise linearisation structures.
