Among the open-literature on pulse-position-modulation (PPM) radiowave wireless communications, this work is first to advance a "blind" spatial-rake receiver with interference-rejection capability. This proposed adaptive "smart antennas" detector uses the signal-of-interest's (SOI) earlier decoded information-symbols to segment earlier collected data into two data-groups: one data-group with the SOI and co-channel-interference and noise, with the other data-group contains only the latter two. These two data-groups' spatial-covariance matrices' generalized-eigenvector maximizes the "blind" spatial beamformer's output signal-to-interference-and-noise ratio (SINR) without prior knowledge of (1) the multi-user co-channel interferers' arrival directions, delays nor powers, (2) the signal-of-interest's (SOI) spatial signature on the receiving sensor-array1, and (3) the mobile's receiving-antennas' nominal/actual array-geometry and gain/phase responses.
