[3G develop] s02-4 DL : 0: 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.

[Program doc] Revisited-DFT-via-Jacket-matrix-and-Its-Applicati DL : 0: 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.

[matlab] simulate DL : 0: Orthogonal STBC [4], [5] has been designed to achieve the spatial diversity offered by multiple transmit and/or receive antennas. The STBC schemes proposed in [4] and [5] are designed for flat-fading channels, which lead to a performance degradation in time- and frequency-selective channels. Our goal is to design efficient STBC schemes to counteract the effects of doubly-selective channels. The basic idea of the proposed STBC for a 21 system is to multiplex the data sequence in two data subsequences and to generate two orthogonal full-diversity subchannels over doubly-selective channels. Then, we apply a scheme that is similar to the Alamouti code.

[Program doc] 20130704_085800 DL : 0: In this letter, we consider a half-duplex amplify-andforward two-way relaying network consisting of two sources with each having a single antenna and one relay having two antennas. For such a system, a distributed orthogonal space-time block code (STBC) is proposed by making use of the Alamouti coding scheme and jointly processing the signals the two antennas at the relay node. Such a code turns out to make the equivalent channel at each source node be a product of the two Alamouti channels and thus, is called distributed concatenated Alamouti STBC.-In this letter, we consider a half-duplex amplify-andforward two-way relaying network consisting of two sources with each having a single antenna and one relay having two antennas.
