摘要
Space-time Doppler (STDO) coding techniques are describe for time-selective channels. In particular, a STDO coded system is capable of achieving a maximum Doppler diversity for time-selective frequency-flat channels. As demonstrated herein, this maximum diversity may be represented as Q+1, where Q is the number of bases in a generalized Basis Expansion Model (BEM) for time-frequency selective channels. In addition, linearly precoded transmissions are described to collect this maximum diversity gain.
