Abstract
Systems and methods are provided for enabling reliable signaling in the presence of strong phase noise and frequency offset. To this end, a method is provided comprising receiving, at a receiver, a communication signal, including data, from a transmitter via a communication channel, and jointly tracking and jointly correcting phase noise errors and frequency errors in the communication signal with a joint detector using an iterative feedback correction process between an output decoder of the receiver and the joint detector.
Claims21
A method comprising:
- receiving, at a receiver, a communication signal, including data, from a transmitter via a communication channel;
- and
- jointly tracking and jointly correcting phase noise errors and frequency errors in the communication signal with a joint detector using an iterative feedback correction process between an output decoder of the receiver and the joint detector.
A receiver in a communication system comprising:
- a filter of the receiver configured to receive a communication signal, including data, from a transmitter via a communication channel;
- and
- a joint detector configured to jointly track and jointly correct phase noise errors and frequency errors in the communication signal using an iterative feedback correction process between an output decoder of the receiver, coupled to an output of the joint detector, and a feedback input of the joint detector.
