Abstract
A method for distortion compensation in a transmission link comprising obtaining information of an amplitude distribution of a signal prior to being transmitted by a transmitter, receiving the transmitted signal at a receiver and determining a received signal amplitude distribution, comparing the received signal amplitude distribution to the amplitude distribution of the signal prior to transmission and using results of the comparison to estimate the AM/AM non-linearity in the transmitter.
Claims15
A method for distortion compensation in a transmission link comprising:
- obtaining statistical information of a signal transmitted by a transmitter;
- receiving the transmitted signal at a receiver;
- comparing statistical information of the received signal to the statistical information of the signal transmitted prior to transmission;
- and
- using results of the comparison to post-compensate at the receiver for non-linear distortions in the transmission link.
A network element comprising:
- a receiver for receiving a signal after transmission from a transmitter;
- a processor configured to:
- obtain statistical information of a signal transmitted by a transmitter;
- receive the transmitted signal at the receiver;
- compare statistical information of the received signal to the statistical information of signal transmitted prior to transmission;
- and
- use results of the comparison to post-compensate at the receiver for non-linear distortions in a transmission link.
