Claim:
Method for interference suppression for time-division multiple access (TDMA) and/or frequency division multiple access (FDMA) transmission, which at least approximately can be described as pulse amplitude modulation, with an arbitrary number of receive antennas, which comprises the following steps: a) filtering of at least one complex-valued received signal r i (k) of one receive antenna with a filter with complex-valued coefficients f i (k) for generation of at least one output signal y i (k); b) forming at least one orthogonal projection of at least one output signal y i (k) onto a vector p i which is assigned to this output signal y i (k); and if the number of output signals y i (k) is one: c1) feeding the output signal y i (k) into a device for detection, especially equalization; or if the number or output signals y i (k) is two or more: d1) summing of a majority, especially all of the output signals y i (k) for forming a sum signal s(k); and d2) feeding the sum signal s(k) into a device for detection, especially equalization, wherein at least two received signals r i (k) are available and the corresponding at least two outputs y i (k) are projected onto identical vectors in step b).
