Quasi-Orthogonal Space-Time Block Codes for Data Transmission over Four and Eight Transmit Antennas with Very Low Feedback Rate
Since the publication of Alamouti’s famous space-time block code for two transmit antennas, various suboptimal space-time block codes for multi-input/multi-output fading channels have been proposed not achieving full diversity at full rate. In this paper we present a family of adaptive, channel dependent, rate-one Extended Alamouti spacetime block codes for four and eight transmit antennas. Onl...
متن کاملSVD Decoding Algorithm of Quasi-orthogonal STBC
Antenna diversity is a practical and effective technique for combating multipath fading in a scattering environment. One attractive method for realizing transmit diversity is to employ quasi-orthogonal spacetime block code (QOSTBC). Based on analyzing the structure and character of the QOSTBC, a novel encoding method of QOSTBC is proposed for four antennas. It enriched the code word of QOSTBC. ...
متن کاملSingle-Carrier Frequency-Domain Equalization for Orthogonal STBC over Frequency-Selective MIMO-PLC channels
In this paper we propose a new space diversity scheme for broadband PLC systems using orthogonal space-time block coding (OSTBC) transmission combined with single-carrier frequency-domain equalization (SC-FDE). To apply this diversity technique to PLC channels, we first propose a new technique for combining SC-FDE with OSTBCs applicable to all dispersive multipath channels impaired by impulsive...
متن کاملTwo complex orthogonal space-time codes for eight transmit antennas
Two complex orthogonal space-time codes for eight transmit antennas" (2004). Two new constructions of complex orthogonal space-time block codes of order 8 based on the theory of amicable orthogonal designs are presented and their performance compared with that of the standard code of order 8. These new codes are suitable for multi-modulation schemes where the performance can be sacrificed for a...
