Abstract
A method and an arrangement for adjusting an antenna, pattern particularly in an SDMA system where a transmitter and a receiver include at least two antennas. Baseband antenna signals are multiplied by coefficients shaping the antenna pattern in order to produce a desired antenna pattern. The phase and strength of a baseband antenna signal are measured. On the basis of the measurement, the differences in phase and strength between the antenna signals are compensated by adjusting the coefficients shaping the antenna pattern.
