Recently, the Liu-Zhang-Wong's Toeplitz space-time block code and the Shang-Xia's Alamouti code-based overlapped space-time block code have been developed to enable coherent full diversity with the linear receivers for a wireless communication system having multiple transmitter antennas and a single receiver antenna. In this paper, such a noncoherent system(More)
A half-duplex amplify-and-forward two-way relay network consisting of two single-antenna sources and N relays with each having two antennas is considered in this paper. For such a system, a tight lower bound of pairwise error probability (PEP) of a maximum likelihood (ML) detector for any distributed linear dispersion code with a fixed average amplifier is(More)
It has been shown that mobile-to-mobile (M2M) communications, where scatters are both around the transmitter and the receiver, may experience more severe channel fading than the fixed-to-mobile (F2M) communications. Double Nakagamim fading is adopted to provide a realistic description of the M2M channel. By using the moment generating function (MGF) based(More)
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 from the two(More)
A novel energy-efficient collaborative Alamouti space-time block code (STBC) design is proposed for a wireless communication system having two transmitter antennas and a single receiver antenna. This new design allows us to have more options for variable-rate modulation for fading channels with enhanced performance for signal transmission than the(More)
A data-aided (DA) carrier recovery (CR) method, which can select different coarse frequency estimation (CFE) paths adaptively according to the initial-estimation of frequency offset, is proposed for the 2nd Generation Digital Video Broadcasting Satellite (DVB-S2) system to accomplish the convergence within at most 400 pilot blocks. The well-known two-step(More)
Asymptotic symbol error probability (SEP) performance with an optimal maximum likelihood (ML) receiver and square quadrature amplitude modulation (QAM) constellations is investigated for two-way amplify-and-forward (AF) half-duplex relaying networks employing distributed Alamouti space-time block codes (DASTCs) recently proposed by Duong et al.
