Both these questions can be answered by assuming a restrictive yet
simple doubly-selective channel model. More specifically, we assume
ablock fading CCE-BEMchannel, which is defined as a block fading
channel where the time-variation subblock to subblock is modeled by a CCE-BEM. Hence, we first develop and analyze the STBC
under this block fading CCE-BEM channel model, and then, we show
how to decode the STBC for real-life channels, which do not exactly
fit this block fading CCE-BEM channel model
