A SYSTEM AND METHOD FOR PAPR REDUCTION BY MEANS OF ARTIFICIAL NOISE IN OFDM TECHNIQUE

摘要

The present invention relates to a system (1) and method (100) for keeping PAPR (Peak-to-Average Power Ratio) value at a desired level by use of artificial noise used for physical layer security in OFDM (Orthogonal Frequency Division Multiplexing) technique. The inventive system (1) consists of data provision unit (2), noise generation unit (3), symbol merge unit (4), conversion unit (5) and control and decision unit (6).
