Abstract

The present disclosure is related to a transmitter, a receiver, a method for transmitting information, and a method of receiving information in a system which simplifies receiver structure and improves the performance in an orthogonal frequency-division multiplexing (OFDM) system. The transmitter comprises a module for generating a passive phase conjugation probe signal for transmission. The receiver comprises a passive phase conjugation module. The method for transmitting information comprises generating a passive phase conjugation probe signal for transmission. The method for receiving information comprises extracting OFDM symbols from a received signal using a method which comprises performing passive phase conjugation on the received signal.
