Power-Balanced Orthogonal Space–Time Block Code
IEEE Transactions on Vehicular Technology, 2008 In this paper, we propose two new systematic ways to construct amicable orthogonal designs (AOD), with an aim to facilitate the construction of power-balanced orthogonal spacetime block codes (O-STBC) with favorable practical attributes. We also show that an AOD can be constructed from an Amicable Family (AF), and such a construction is crucial for ...

Simple scheme combining space-time coded OFDM with multi-dimension beamforming
Tongxin xuebao, 2006 A simple and efficient combining scheme was proposed for MIMO-OFDM system, which jointly designed space time block codes and multi-dimension eigen-beamforming according to second-order statistics of channels. The proposed scheme would achieve the maximum

Space-Time Coded Spatial Modulated Physical Layer Network Coding for Two-Way Relaying
, 2014 Using the spatial modulation approach, where only one transmit antenna is active at a time, we propose two transmission schemes for two-way relay channel using physical layer network coding with space time coding using Coordinate Interleaved Orthogonal ...

L2 Orthogonal Space Time Code for Continuous Phase Modulation [PDF]
, 2008 To combine the high power efficiency of Continuous Phase Modulation (CPM) with either high spectral efficiency or enhanced performance in low Signal to Noise conditions, some authors have proposed to introduce CPM in a MIMO frame, by using Space Time ...

Differential space-time block-coded OFDMA for frequency-selective fading channels [PDF]
, 2003 Combining differential Alamouti space-time block code (DASTBC) with orthogonal frequency-division multiple access (OFDMA), this paper introduces a multiuser/multirate transmission scheme, which allows full-rate and full-diversity noncoherent ...

EURASIP Journal on Advances in Signal Processing, 2004 In the downlink of DS-CDMA, frequency-selectivity destroys the orthogonality of the user signals and introduces multiuser interference (MUI). Space-time chip equalization is an efficient tool to restore the orthogonality of the user signals and suppress

Equivalent-Capacity-Based Design of Space-Time Block-Coded Sphere-Packing-Aided Multilevel Coding [PDF]
, 2007 A multilevel coding (MLC) scheme invoking sphere packing (SP) modulation combined with space time block coding (STBC) is designed. The coding rates of each of the MLC component codes are determined using the so-called equivalent capacity based ...
