【 摘 要 】

References(8)This paper aims to design a new transceiver with a signal space diversity (SSD) in layered multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems. To this end, a enhanced coordinate interleaver (E-CI) that swaps a random pair of subcarriers is first proposed in order to realize readily the detection ordering required for a layered MIMO processing at the receiver. A enhanced maximum likelihood (E-ML) detection is also proposed in order to provide SSD gain after the MIMO detection processing. The performance of layered MIMO-OFDM system is evaluated and compared with that of MIMO-OFDM systems without the E-CI and E-ML detection over a time-varying Typical Urban (TU) channel.
