Abstract: Power amplification and spectral e±ciencies could be optimized with transmitter structures employing several branches, each one associated to a signal component of the symbol to be transmitted, with an ampli¯er directly connected to an antenna or an antenna array. Under these conditions the signal components transmitted by the several branches are associated to di®erent beams to increase the separation among data streams from di®erent users. However, even in these conditions interference among users can occur due to superposition of radiation beams carrying signal components from di®erent users. Since the physical security level assured by these structures is not negatively a®ected, it is crucial the assessment of interference e®ects in such systems. Under certain limits in misalignments, simulation results show that beam interference has low impact on system performance.
