A Fast-Decodable, Quasi-Orthogonal Space-Time Block Code for 4x2 MIMO

چکیده
In this paper we present a new family of fullrate space–time block codes for 4 × 2 MIMO. We show how, by combining algebraic and quasi-orthogonal properties of the code, reduced-complexity maximum-likelihood decoding is made possible. In particular, the sphere decoder search can be reduced from a 16to a 12-dimensional space. Within this family, we found a code that outperforms all previously proposed codes for 4× 2 MIMO.

Single-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 کاملCooperative Orthogonal Space-Time-Frequency Block Codes over a MIMO-OFDM Frequency Selective Channel
In this paper, a cooperative algorithm to improve the orthogonal space-timefrequency block codes (OSTFBC) in frequency selective channels for 2*1, 2*2, 4*1, 4*2 MIMO-OFDM systems, is presented. The algorithm of three node, a source node, a relay node and a destination node is formed, and is implemented in two stages. During the first stage, the destination and the relay antennas receive the sym...
متن کاملQuasi-Orthogonal Space-Time Block Code
Quasi-Orthogonal Space-Time Block Code presents an up-to-date, comprehensive and in-depth discussion of an important emerging class of space-time codes, called the Quasi-Orthogonal STBC (QO-STBC). Used in Multiple-Input Multiple-Output (MIMO) communication systems, they provide transmit diversity with higher code rates than the well-known orthogonal STBC (OSTBC), yet at lower decoding complexit...
متن کاملSingle-symbol and Double-symbol Decodable STBCs for MIMO Fading Channels
For a communication system operating in a fading environment, receive antenna diversity is a widely applied technique to reduce the detrimental effects of multi path fading. But as this makes the receiver complex and costly, is generally used exclusively at the base station. Recently a combination of transmit and receive diversity has been suggested as a more effective solution to the above pro...
متن کاملAchieving Low-Complexity Maximum-Likelihood Detection for the 3D MIMO Code
The 3D MIMO code is a robust and efficient space-time block code (STBC) for the distributed MIMO broadcasting but suffers from high maximum-likelihood (ML) decoding complexity. In this paper, we first analyze some properties of the 3D MIMO code to show that the 3D MIMO code is fast-decodable. It is proved that the ML decoding performance can be achieved with a complexity of O(M) instead of O(M)...
