摘要：A communications system includes a ground hub, mobile airborne platforms,and a user terminal. The ground hub includes an antenna system, a beam-forming systemand a baseband processor. The antenna system receives return-link signals radiated
respectively by the mobile airborne platforms. The return-link signals correspond tosignal streams transmitted by the user terminal and received by the mobile airborneplatforms. The signal streams correspond to data streams including a known pilot codestream. The beam-forming system forms beams to receive the return-link signals andtransforms the received return-link signals into baseband signals. The baseband
processor includes adaptive equalizers to equalize the baseband signals and a wavefrontdemultiplexing processor to perform a wavefront demultiplexing transform on theequalized baseband signals to produce recovered versions of the data streams.
