Space Time Coding for Mimo Systems
With space-time codes (STC) the same information is transmitted in appropriate manner simultaneously from different transmit antennas to obtain transmit diversity. The main idea of transmit diversity is that if a message is lost in a channel with probability p and we can transmit replicas of the message over n independent such channels, the loss probability becomes p. Using diversity, more reli...
متن کاملMIMO Channels and Space-Time Coding
Outline: • Capacity of MIMO Channels: We discuss the information theo-retic bases for the capacity arguments of MIMO channels and present fundamental results and methods. • Channel Modeling and Realizable Capacity: We discuss simple ray-tracing channel models and study the capacity of these artificially generated channels. Basic conclusions on the behavior of real-world MIMO channels are drawn....
متن کاملA space-time coding approach for RFID MIMO systems
This paper discusses the space-time coding (STC) problem for RFID MIMO systems. First, a mathematical model for this kind of system is developed from the viewpoint of signal processing, which makes it easy to design the STC schemes. Then two STC schemes, namely Scheme I and Scheme II, are proposed. Simulation results illustrate that the proposed approaches can greatly improve the symbol-error r...
متن کاملSpace-time coding techniques with bit-interleaved coded modulations for MIMO block-fading channels
The space-time bit-interleaved coded modulation (ST-BICM) is an efficient technique to obtain high diversity and coding gain on a block-fading MIMO channel. Its maximum-likelihood (ML) performance is computed under ideal interleaving conditions, which enables a global optimization taking into account channel coding. Thanks to a diversity upperbound derived from the Singleton bound, an appropria...
متن کاملNear Outage Limit Space-Time Coding for MIMO channels
We study simple space-time coding techniques for multiple-input multiple-output (MIMO) quasi-static channels (2Tx and 4Tx) capable of achieving near outage limit performance. The core of our space-time code is an h-π-diagonal state multiplexer that guarantees full diversity and a quasi-optimal coding gain on the MIMO channel. The whole range of word error probability is attained at signal-to-no...
