Abstract
A plurality of bit stream formatters formats and codes the digital information signals that are to be transmitted. A symbol generator generates I and Q symbols from the formatted information signals. These symbols are input to the beamforming matrix that is connected directly to the symbol generators. The beamforming matrix generates baseband beam signals from the I and Q symbols. Baseband, pulse-shaping, low-pass filters are connected to the beamforming matrix. The low-pass filters each generate an antenna feed signal from each of the baseband beam signals.
