ABSTRACT:
A method for combining a reference signal with a data signal is disclosed. A multiplexed data signal is received. A demultiplexer is applied to the data signal. The data signal is encoded. A linear transformation is applied to the data signal which projects the data signal into a null-space of a plurality of reference signals. The encoded data signal is summed with the reference signal. The summation of the data signal and the reference signal is orthogonally modulated. The combined reference signal and data signal is transmitted to a receiver.
