This paper explains how fractional cyclic moments of CPFSK signals can be used in adaptive beamforming. It is shown that CPFSK signals have non-zero fractional cyclic moments because they generate spectral lines when they are raised to the inverse of its modulation index, which is generally a fractional number. To exploit this property, an optimization criterion is proposed to compute the antenna coefficients that maximize the output SINR. The resulting technique is blind because it does not need to know the transmitted symbols: only the carrier frequency, the symbol rate and the modulation index is required
