Complex field coded MIMO systems: performance, rate, and trade-offs
نویسندگان
چکیده
The quest for reliable high-rate wireless links motivates fading-resilient and bandwidth-efficient communication systems capable of capitalizing on available forms of diversity. This tutorial focuses on linear complex field (LCF) coding—a powerful tool that complements the traditional Galois field (GF) coding, in enabling diversity transmissions over singleand multi-antenna fading channels. Performance and capacity analyses are provided, along with systematic guidelines for constructing LCF encoders, and options available to the designer for selecting LCF decoders. Emphasis is placed on high-performance and high-rate designs, and the emerging performance-rate-complexity trade-offs. Copyright 2002 John Wiley & Sons, Ltd.

Defining Pathways and Trade-offs Toward Universal Health Coverage; Comment on “Ethical Perspective: Five Unacceptable Trade-offs on the Path to Universal Health Coverage”
The World Health Organization’s (WHO’s) World Health Report 2010, “Health systems financing, the path to universal coverage,” promoted universal health coverage (UHC) as an aspirational objective for country health systems. Yet, in addition to the dimensions of services and coverage, distribution of coverage in the population, and financial risk protection highlighted by the report, the conside...
متن کاملChannel estimation for MIMO systems using data-dependent superimposed training
Multiple antenna systems have been shown to increase system capacity and provide resiliency to random fading. However, these attractive features require accurate channel estimation. This can be achieved by time-division multiplexing (TDM) an adequately large training sequence. An alternative to TDM training is the superimposed training (ST) scheme which trades-off power for bandwidth (or rate)....
متن کاملMulti attribute augmentation for Pre-DFT Combining in Coded SIMO- OFDM Systems
For coded SIMO-OFDM systems, preDFT combining was shown to provide a good trade-off between error-rate performance and processing complexity. Max-sum SNR and max-min SNR are two reasonable ways for obtaining these combining weights. In this paper multi attribute augmentation is Employed to further reveal the suitability and limitation of these two criteria. The results show that neither max-sum...
متن کاملAn Efficient Adaptive Space Time Coding Scheme for MIMO-OFDM Systems
Within the framework of the Stingray Project, a Hiperman compatible MIMO system, three architectures with different rate-one Space-Time Codes (STC) are presented and their performance assessed. Viewing beam-forming and Alamouti as the two extreme cases of the trade-offs between performance/ complexity/feedback-requirements, an efficient scheme is proposed that reduces complexity and feedback re...

The combination of the orthogonal frequency-division multiplexing (OFDM) technique and the multiple-input multiple-output (MIMO) architecture has emerged as a promising candidate for future wireless communications. The Space-time block coding (STBC) technique permits to fully take advantage of MIMO-OFDM systems and to effectively improve the channel capacity and the spatial diversity. The Golde...
