چکیده
Gerhard Bauch and Joachim Hagenauer Institute for Communications Engineering (LNT) Munich University of Technology (TUM) Abstra t | We give an introduction to wireless systems with multiple transmit and receive antennas. Using multiple antenna systems is motivated by results on the capacity of multiple-input-multipleoutput (MIMO) channels. We describe different approaches to exploit these capacities like Bell Labs Layered Space-Time Architecture (BLAST), which we append by FEC coding and turbo processing, and transmit antenna diversity using space-time codes. The focus of the paper is on space-time codes. We describe the diversity effect of space-time trellis codes and space-time block codes using equivalent channel models and discuss if the MIMO channel capacity can be fully exploited using those techniques.

Super-Orthogonal Space-Time Turbo Transmit Diversity for CDMA
Studies have shown that transmit and receive diversity employing a combination of multiple transmit-receive antennas (given ideal channel state information (CSI) and independent fading between antenna pairs) will potentially yield maximum achievable system capacity. In this paper, the concept of a layered super-orthogonal turbo transmit diversity (SOTTD) for downlink directsequence code-divisio...
متن کاملPerformance analysis of turbo codes in quasi-static fading channels
The performance of turbo codes in quasi-static fading channels both with and without antenna diversity is investigated. In particular, simple analytic techniques that relate the frame error rate of a turbo code to both its average distance spectrum as well as the iterative decoder convergence characteristics are developed. Both by analysis and simulation, the impact of the constituent recursive...

This paper discusses the performance of antenna selection technique in space time turbo coded MIMO-OFDM systems. Multiple-input multiple-output (MIMO) technology can either increase the data rate through spatial multiplexing or improve the reliability through diversity. Space-time turbo codes (STTC) have been proposed to provide robust communications in MIMO wireless environment. STTC technique...
متن کاملHow to obtain turbo gains in coherent and non-coherent orthogonal transmit diversity
— We consider turbo detection for coherent and non-coherent orthogonal transmit diversity. The turbo iterations are done between a convolutional code and the diversity combiner. We show that due to the orthogonal structure of the space-time block codes, extrinsic information which enables turbo gains can only be obtained for special symbol mappings. Such optimized symbol mappings are given for ...
متن کاملA Survey on Space-Time Turbo Codes
As wireless communication systems look intently to compose the transition from voice communication to interactive Internet data, achieving higher bit rates becomes both increasingly desirable and challenging. Space-time coding (STC) is a communications technique for wireless systems that inhabit multiple transmit antennas and single or multiple receive antennas. Space-time codes make use of adv...
