A new algorithm is herein proposed to "blindly" suppress co-channel interference and to detect the signal-of-interest (SOI) for peer-to-peer mobile transceivers using M-ary frequency-shift-keying (MFSK) fast frequency-hop (FFH) code-division multiple-access (CDMA). This algorithm implements a two-dimensional space-frequency "blind" beamformer over the direction-of-arrival and the frequency-hop set. This proposed blind adaptive "smart antennas" signal processing scheme attempts to maximize the beamformer's output signal-to-interference-and-noise ratio (SINK) without prior knowledge of (1) the (possibly overlapping) hop-sequences of the multi-user Co-channel interferers, (2) the fading channel's (possibly spatially and temporally decorrelated) space-time impulse response, and (3) the mobile receiver antennas' nominal or actual gain/phase responses. The proposed scheme can also reject "spectral splatter" and can exploit any spatially decorrelated fading across the receiving antennas. This proposed scheme requires no additional bandwidth but assumes (rather reasonably) that the strongest co-channel interferers persist for at least a few information symbols.
