Accessing cp channels with lp terminals via wavefront multiplexing

A linearly polarized transmitting terminal comprising:

• a polarization converter to convert polarization of first and second input signals to first and second output signals, the polarization converter comprising:
• a wavefront muxing processor receiving first and second input signals to generate first and second output signals on first and second communication channels, respectively, the first and second output signals being at a common frequency slot and having relative differential amplitude and phase delays;
• and
• an amplitude and phase adjustment element located at one of the first and second communication channels to adjust the relative differential amplitude and phase delays using an adjustment amount to reduce interference in the first and second communication channels,
• wherein the first output signal is a weighted sum of the first input signal and the second input signal that is phase shifted by a second phase shift,
• wherein the second output signal is a weighted sum of the second input signal and the first input signal that is phase shifted by a first phase shift;
• and
• a transmitter having first and second feeds to transmit the first and second output signals, respectively to a transponding satellite.
