Patent Images
1. A communication device for enabling phase tracking, comprising:
- a processor;
memory in electronic communication with the processor;
instructions stored in the memory, the instructions being executable to;
generate a plurality of pilot symbols, wherein the pilot symbols conform to a rank-deficient pilot mapping matrix that has less than full rank and enables comparing a phase of a repeated pilot symbol set to a phase of an original pilot symbol set to determine a phase estimate; and
transmit the plurality of pilot symbols during a training period.
