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;

Single Input Multiple Output techniques for

Currently, there are three broadband :LUHOHVVV/RFDOO$UHD1HWZRUNV (WLAN) standards harmonised at the physical layer (based on OFDM) that operate in the 5 GHz band, i.e. ETSI BRAN HL/2 in Europe, IEEE 802.11a in the USA and ARIB MMAC HiSWAN in Japan. This paper focuses on the use of adaptive antennas for HL/2 [ETSI00]. The system shall be adapted to work in different propagation and interference ...

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...
