Optimal Code Constructions for SIMO-OFDM Frequency Selective Fading Channels
Hsiao-Feng Francis Lu · 2007
A SIMO-OFDM system with nrreceive antennas and Q subcarriers is considered in this paper. Under a frequency-selective Rayleigh fading channel with L multipaths, Lout(r) = Lnr(1-r). Finally we prove that a newly constructed multi-block space-frequency code can be used to reach the optimal diversity-multiplexing gain tradeoff of this channel with optimal diversity gain d-(r) sime Lnr(1-r).
