Abstract This paper deals with the problem of adaptive array beamforming for cyclosta-tionary signals-a novel robust cyclostationary space-time beamforming algorithm. In this algorithm, multiple lag parameters and the spectrum correlation property are used to exploit the cyclic statistical information and time domain characteristics of signals sufficiently and ef-fectively. Moreover, this method remedies the lack of space domain information, and it is an extension from space domain to space-time domain. Therefore the ability to select the desired signals and supress the noise and interfering signals is improved. The simulation results show the effectiveness and robustness of the algorithm.
