Abstract
A transmitter may be configured to generate a reference signal having a non-constant envelope for nonlinearity estimation by a receiver. The transmitter may transmit the reference signal. A receiver may be configured to receive, from the transmitter, the reference signal having the non-constant envelope. The receiver may estimate at least one nonlinearity characteristic based on the reference signal having the non-constant envelope. The receiver may transmit feedback based on the at least one nonlinearity characteristic and/or perform at least one digital post distortion (DPoD) operation based on the at least one nonlinearity characteristic.
Claims20
A method of wireless communication for a first wireless communications device, comprising:
- receiving a signal having a non-constant envelope from a second wireless communications device, the signal having the non-constant envelope being modulated to have a first dynamic range that is higher than a second dynamic range of another signal having a constant envelope;
- and
- determining nonlinearity information based on the signal having the non-constant envelope.
An apparatus for wireless communications, comprising:
- a memory;
- and
- at least one processor coupled to the memory and configured to:
- receive a signal having a non-constant envelope from a second wireless communications device, the signal having the non-constant envelope being modulated to have a first dynamic range that is higher than a second dynamic range of another signal having a constant envelope;
- and
- determine nonlinearity information based on the signal having the non-constant envelope.
A non-transitory, computer-readable medium storing computer-executable code for wireless communications, the code when executed by a processor cause the processor to:
- receive a signal having a non-constant envelope from a second wireless communications device, the signal having the non-constant envelope being modulated to have a first dynamic range that is higher than a second dynamic range of another signal having a constant envelope;
- and
- determine nonlinearity information based on the signal having the non-constant envelope.
