In this paper, frequency-domain relay processing in a two-hop transmission system is investigated. The relay is constrained to be "non-regenerative"; that is, the relay is only allowed to perform a symbol-by-symbol memoryless transformation of its received signals. Multicarrier modulation, e.g., orthogonal frequency division multiplexing (OFDM), is utilized… CONTINUE READING
