Description: This paper deals with the following issue in space time block coding (STBC) design: over a time selective channel,which scheme performs better, orthogonal STBC (O-STBC) or non-orthogonal STBC (NO-STBC)? It is shown that under time-selectiveness, once the vehicle speed has risen above certain value, NO-STBC always outperforms O-STBC - across the whole SNR range. Also, considering that all the existing NO-STBC schemes have been investigated under quasi-static channels only, a new simple receiver was derived for the NO-STBC system under time-selective channels.

Description:
The zip file contains several matlab files. These files implement the optimal vlassifier (optimal_classifier.m), a sub-optimal classifier (SOS_STBC_Classifier.m) which is based on Second Order Statistic and a low-complexity sub optimal code-parameter classifier (CP_Classifier.m). See reference [1] for the theoretical background.
Example: To create the fig 3,4 and 5 of the paper, call the routine:

Description: This paper analyzes the performance of phase
feedback, quasi-orthogonal space-time block codes (QOSTBC)
and Extended OSTBC systems in the presence of
feedback delay, feedback error and amount of channel
feedback. Space-time code constructed for nT transmit
antennas can easily be extended to nT×p antennas transmit
based on a feedback of only p-1 bits. This paper shows that
more feedback bits (more than p-1 bits) in ideal system
(EOSTBC system with no feedback delay and no feedback
error) cause no more considerable performance in the
system. But in the inaccurate feedback information with
increasing feedback bits from p-1 bits decrease sensitivity of
system and increase performance considerably. This paper
obtains an upper bound for phase feedback error respect to
number of feedback bits. Moreover it shows that the system
can select adaptively one of the three modes, phase only
feedback, EO-STBC and QO-STBC with respect to
reliability and amount of feedback information.

Description: The paper proposes address a new representation of the DFT matrix via the Reverse Jacket Transform(RJT) based on the WHT, and propose a simple approach for space time block codes (STBC) design. Using the proposed approach (J=H.S) the quasi-orthogonal STBC may be designed easily. Especially the performance of the code can be improved.

Description: In this paper, a simple transmit diversity scheme using
two transmitting and two receiving antennas for STBC structure
is presented. Moreover, a detection algorithm with iterative
interference cancellation for STBC-OFDM/OQAM system is
proposed to improve bit error ratio performance. Simulation
results prove that the proposed detection algorithm is an effective
algorithm for STBC-OFDM/OQAM system.

Description: In this paper, we develop a novel STBC for multi-antenna transmissions over doubly-selective channels. The proposed STBC is designed
for a multiple-input single-output (MISO) system with two transmit
antennas and one receive antenna, i.e., a 2 1 system, but the ideas
can be extended to a general multiple-input multiple-output (MIMO)
system. The proposed technique can be interpreted as the extension
of the Alamouti code to doubly-selective channels, and relies on a
joint time–frequency reversal of the transmitted sequences.

Description: Signal identification represents the task of a receiver
to identify the signal type and its parameters, with applications
to both military and commercial communications. In this paper,
we investigate the identification of spatial multiplexing (SM) and
Alamouti (AL) space-time block code (STBC) with single carrier
frequency division multiple access (SC-FDMA) signals, when
the receiver is equipped with a single antenna. We develop a
discriminating feature based on a fourth-order statistic of the
received signal, as well as a constant false alarm rate decision
criterion which relies on the statistical properties of the feature
estimate. Furthermore, we present the theoretical performance
analysis of the proposed identification algorithm. The algorithm
does not require channel or noise power estimation, modulation
classification, and block synchronization. Simulation results show
the validity of the proposed algorithm, as well as a very good
agreement with the theoretical analysis.
