Systems and Methods for Communicating by Modulating Data on Zeros

A method for establishing channel estimation for duplex data communications using a MOZ (Modulation of Zeros) modulation scheme and then transitioning to another modulation scheme, the method comprising:

• exchanging a first data communication between a transmitter and a receiver using a first modulation scheme,
• where the first modulation scheme is a MOZ scheme in which a plurality of encoded bits are encoded in the zeroes of the z-transform of the discrete-time baseband signal used to generate a first continuous-time signal, and
• where the first continuous-time signal forms a portion of the first data communication that is transmitted from the transmitter to the receiver;
• commencing, after exchanging the first data communication, communication between the transmitter and the receiver using a second modulation scheme, where the second modulation scheme is different from the first modulation scheme.

A wireless communication system, comprising:

• A transmitter configured to exchange a first data communication with a receiver using a first modulation scheme,
• where the first modulation scheme is a MOZ (Modulation of Zeros) scheme in which a plurality of encoded bits are encoded in the zeroes of the z-transform of the discrete-time baseband signal used to generate a first continuous-time signal, and
• where the first continuous-time signal forms a portion of the first data communication that is transmitted from the transmitter to the receiver;
• where the transmitter is further configured to commence, after exchanging the first data communication, communication with the receiver using a second modulation scheme, where the second modulation scheme is different from the first modulation scheme.
