A method of increasing utilization of user link bandwidth for a code division multiple access communications system is disclosed that includes the steps of selecting a set of orthogonal complex codes each having a code length that is greater than a code length of an optimum real code and less than or equal to a number of antenna elements in an antenna array of the feeder link. The architecture compensates for performance asymmetry between ICs communicating over a bidirectional lane by instantiating relatively complex transmit and receive equalization circuitry on the higher-performance side of the lane. Data is transferred from metadata elements of the source data model to variables of a virtual document, based on a mapping that has been previously made.
