Diagonal algebraic space-time block codes
IEEE Transactions on Information Theory, 2002Summary: We construct a new family of linear space-time (ST) block codes by the combination of rotated constellations and the Hadamard transform, and we prove them to achieve the full transmit diversity over a quasi-static or fast fading channel. The proposed codes transmit at a normalized rate of 1 symbol/\(s\).

On non-linear space-time block codes
IEEE International Conference on Acoustics Speech and Signal Processing, 2002A number of space-time block codes have been proposed for the quasi-static, flat-fading channel with coherent receiver. All of these block codes are linear codes, i.e., the encoded codeword is a linear function of the input scalar symbols. Here we propose new non-linear space-time block codes, i.e., the codewords are non-linear functions of the input ...

High Rate Space Time Block Codes
IEICE Transactions on Communications, 2006High Rate Space-Time Block Codes (HR-STBCs) with greater than 1 symbol/transmission and simple decoding schemes are proposed. The HR-STBC demonstrates 3 dB E b /N 0 gain at BER = 10 -3 compared with the conventional STBC when three transmit antennas and two receive antennas are utilized.

Performance of space-time block coding and space-time trellis coding for impulse radio
IEEE Global Telecommunications Conference, 2004. GLOBECOM '04., 2005Ultra wideband (UWB) systems have attracted a lot of research interest lately, owing to their appealing features in short-range mobile communications. These features include low power peer-to-peer transmissions, multiple access communications, high data rates, and precise positioning capabilities.

Equivalent codes and optimality of orthogonal space-time block codes
2011 Conference Record of the Forty Fifth Asilomar Conference on Signals, Systems and Computers (ASILOMAR), 2011An equivalent model of a multiple-input multiple-output (MIMO) communication system with orthogonal space-time block coding (OSTBC) is proposed based on a newly found connection between OSTBCs and Euclidian codes. A new asymptotic upper bound on the symbol error rate (SER) of OSTBC, which is based on distance spectra of the introduced equivalent ...

Noncoherent space-time block coded modulation
2004 IEEE International Conference on Communications (IEEE Cat. No.04CH37577), 2004Unitary space-time modulation is well tailored for flat fading channels where the noncoherent receiver is used. In this paper, we propose a novel scheme of unitary space-time modulation, called noncoherent space-time block coded modulation, by using the set partitioning of signal sets and multilevel coding.

Space time block codes with turbo codes
2011This paper aims to provide efficient solutions to improve the power efficiency, like implementation of schemes using MIMO (Multiple-Input Multiple-Output), with error correction codes. Thanks to the union of these two techniques is possible to obtain a low error probability with low power consumption. This paper shows STBC (Space Time Block Codes) with
