Multiple-Input Multiple-Output (MIMO) Linear Systems Extreme Inputs/Outputs

Special Issue: Multiple-Input Multiple-Output (MIMO) Communications

The idea of using multiple transmit and receive antennas in wireless communication systems is one of the most important breakthroughs in communication theory during the last decade. Popularly referred to as MIMO technology, this concept can greatly improve data throughput and link performance in wireless networks. In principle, a MIMO system can operate in, or anywhere between, one of the two p...

Othogonal Waveform Design for Multiple-Input Multiple-Output (MIMO) Radar

An effective numerical approach is developed for orthogonal waveform design for Multiple-Input Multiple-Output (MIMO) radar. The Doppler shift tolerance is considered in the design cost function. The design results indicate that the Doppler tolerance of the designed orthogonal waveforms is markedly improved. Keywords-MIMO radar; waveform design; Doppler effect;

Multiple-Input Multiple-Output Wireless Systems

The paper gives an overview of the multiple-input multiple-output (MIMO) systems and discusses their benefits enabling an increase in the system capacity and an increase of system reliability. The former is attained by signal multiplexing and the later by space encoding. The basic algorithms required for a proper operation of the MIMO systems, i.e. channel estimation, equalisation, optimal and ...

Linear Precoding and Decoding for Multiple Input Multiple Output (mimo) Wireless Channels

Space-time coding and spatial multiplexing are prime candidates for achieving high data rates and link quality in multiple-input multiple-output (MIMO) wireless links. However, both the schemes assume no channel knowledge at the transmitter. In a number of applications, channel knowledge can be made available at the transmitter. A natural question to ask is how to use these channel estimates to...
