  In mobile cellular networks, it is estimated that more than 60% of voice and
data services occur indoors. Therefore, cellular network operators have shown
an unprecedented interest in research on femtocell systems from various aspects
to extend the indoor wireless coverage for providing high-quality and high
data-rate wireless multimedia services contents. In an effort for reducing the
bit-error probabilities (BEPs) and also increasing bit/symbol capacity of
bandwidth limited error-prone wireless channels in femtocell propagation areas,
this paper presents the performance of a promising candidate technology
designed based on the state-of-the-art techniques. The performance of powerful
space-time turbo codes (STTCs) based on serial concatenation of quadratic
interleaved codes (SC-QICs) with the optimal and also suboptimal decoding
algorithms, in conjunction with orthogonal space-time block codes (OSTBCs) have
been presented in this contribution for wireless multiple-input single-output
(MISO), and multiple-input multiple-output (MIMO) semi-femtocells.
