Abstract :
We present a new transmission scheme which apply the linear dispersion code (LDC) to a single transmit antenna in the OFDM system. Our scheme, named virtual LDC, transfers the LDC substreams through the multiple uncorrelated OFDM subchannels. The virtual LDC scheme can achieve the coding and diversity advantage as well as LDC in MIMO. It is shown that the virtual LDC scheme can improve the BER performance compared with plain OFDM system.
