Abstract: A method of expanding a capacity of a single radio channel, and a radio. The method includes receiving a primary signal and a secondary signal. The method also includes a transmitter modulating the primary signal and the secondary signal. The method further includes the transmitter scaling a power of the secondary signal below a power of the primary signal to create a power differential. The method also includes the transmitter offsetting a carrier frequency of the secondary signal from a carrier frequency of the primary signal to create a carrier frequency offset. The method further includes the transmitter combining the primary signal and the secondary signal to generate a composite signal. The method also includes the transmitter transmitting the composite signal within the single radio channel via an antenna. The antenna is coupled to the transmitter.

Abstract: Systems, devices, and methods to improve signal detection of a receiver in communication systems, including receiving a signal having one or more distorted versions of a predetermined waveform as well as processing the received signal with a plurality of eigenfilters generated from eigenvectors of a covariance matrix of the predetermined waveform. Further a correlation output is generated by further processing the received signal with at least one matched filter formed from an eigenfiltered version of the predetermined waveform and identifying at least one peak in the correlator output. The peak may be used to improve performance of the receiver.
