The disclosed systems, structures, and methods are directed to a wireless local area network (WLAN) transmission architecture and transmitting methodology that combines space-time block code (STBC) encoding techniques with semi-orthogonal multiple access (SOMA) schemes to improve throughput rate ...
Space-time block codes are a remarkable modulation scheme discovered recently for the multiple antenna wireless channel. They have an elegant mathematical solution for providing full diversity over the coherent, flat-fading channel. In addition, they require extremely simple encoding and decoding. Althoug...
This chapter provides a tutorial overview of important aspects of space-time block codes (STBCs). After describing the necessary preliminaries it deals with STBCs with low maximum-likelihood (ML) decoding complexity. Multi-group low ML decoding complexity decodable codes are discussed along with thei...
Space-time block coding is used for data communication in fading channels by multiple transmit antennas. Message data is encoded by applying a space-time block code and after the encoding the data is break into `n' streams of simultaneou... S Narain,SH Saeed 被引量: 0发表: 2014年 加载更...
Based on the self-interference of quasi-orthogonal space-time block code (QOSTBC), two partial feedback close-loop QOSTBC design methods are proposed. 针对准正交空时分组码(QOSTBC)存在自干扰的特性,提出了两种基于部分反馈的闭环QOSTBC的设计方法,这两种反馈方法可以减小QOSTBC的自干扰,提高QOSTBC的误...
A method for wireless communications includes encoding a training sequence thereby producing an encoded training sequence, placing the encoded training sequence in a first part of a multi-part preamble, and transmitting the multi-part preamble using a first transmit antenna and a second transmit ...
Space- time block codes are code technologies which provide a new paradigm for transmitting over Rayleigh fading channels using multiple antennas. An overview of the space- time codes is made in terms of the system model, encoding and decoding algorithm, design criterion, concatenation of space- ...
To improve transmission diversity, space-time block coding in each of the two transmission paths has been developed, as described in Alamouti, “Space-Time Block Coding, A Simple Transmit Diversity Technique for Wireless Communications”, IEEE Journal on Selected Areas in Communications, Volume 16, ...
