Method and system for generating multiple radiation patterns using transform matrix

A system comprising:

• an antenna array comprising a plurality of antennas configured to provide a first radiation pattern for carrying a predetermined traffic channel associated with a predetermined mobile terminal based on first antenna weights and a second radiation pattern for carrying a control channel associated with one or more mobile terminals based on second antenna weights,
• wherein the first radiation pattern is beamformed for the predetermined mobile terminal and the second radiation pattern is omni-directional within a predetermined coverage area;
• a transform matrix configured to be coupled to the antenna array and to transform one or more inputs into one or more outputs according to a transform function that transforms the first antenna weights and second antenna weights into respective first and second input weights that are applied to first and second sets of signals, respectively, to be transmitted, and to output signals to the antennas of the antenna array with predetermined phases and magnitudes in order to generate the first and second radiation patterns simultaneously;
• and
• a transmitter configured to provide the first set of signals to be transmitted with the first radiation pattern and the second set of signals to be transmitted with the second radiation pattern to inputs of the transform matrix.
