چکیده

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. • Space-Time Coding: We introduce the basics of space-time coding and modulation methods, such as orthogonal designs, unitary space-time codes, group space-time codes. We discuss error performance measures, and optimal and sub-optimal decoding algorithms. • Space-Time Communications Systems: We discuss basic layer-ing methods and the addition of error control coding to space-time systems. We show how complex decoders work and how they perform .

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...

Cooperative 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...

Near 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...

Space Time Block Codes for MIMO systems: History to Recent Developments

Multi Input Multi Output (MIMO) communication is a proven technique to increase the throughput, diversity gain and increase the energy gain by reducing the energy consumption of the wireless network. Space time diversity used in MIMO systems is a technique to mitigate multipath fading. The same information is transmitted over multiple channels that fade independently. So, space time diversity i...

Space-Time Block Coding (STBC) for Multiple Transmit Antennas over Time Selective Fading Channels

A study of space-time block coding in analytical form-multiple input and multiple output (STBC-MIMO) system was done in various cases. Initially, a basic Alamouti scheme for encoding was illustrated. Then, the performance of proposed STBC-MIMO was studied under varying a number of transmitting antennas, varying number of receiving antennas, varying channels, various modulations and also at vary...
