A transmitter system comprises a mapper configured to map data bits and power information to multiple subcarriers, producing mapped information. A first-level modulator converts this mapped information into subcarrier specifications, each defined by a complex number indicating amplitude and phase. The system includes multiple data stream / power channel digital paths, each with a frequency selector that processes a portion of the subcarrier specifications. An orthogonal subcarrier generator translates these specifications from frequency to time domain, generating baseband real and imaginary signals. A second-level modulator processes these signals with intermediate-frequency sine and cosine waves to produce IF I and IF Q signals. A beamformer modifies the phase and / or amplitude of these signals across multiple antenna channels, creating directed signals. Finally, a combiner adds output signals from each data stream / power channel digital path, directing them to corresponding antenna channel modules, facilitating efficient transmission across multiple channels.
