  In this paper, a new receiver structure that is intended to detect the
signals from multiple adjacent satellites in the presence of other interfering
satellites is proposed. We tackle the worst case interference conditions, i.e.,
it is assumed that uncoded signals that fully overlap in frequency arrive at a
multiple-element small-size parabolic antenna in a spatially correlated noise
environment. The proposed successive interference cancellation (SIC) receiver,
denoted by SIC Hy/ML, employs hybrid beamforming and disjoint maximum
likelihood (ML) detection. Depending on the individual signals spatial
position, the proposed SIC Hy/ML scheme takes advantage of two types of
beamformers: a maximum ratio combining (MRC) beamformer and a compromised array
response (CAR) beamformer. The performance of the proposed receiver is compared
to an SIC receiver that uses only MRC beamforming scheme with ML detection for
all signals, a joint ML detector, and a minimum mean square error detector. It
is found that SIC Hy/ML outperforms the other schemes by a large margin.
