MIMO Radar Ambiguity Properties and Optimization Using Frequency-Hopping Waveforms [PDF]
, 2008 The concept of multiple-input multiple-output (MIMO) radars has drawn considerable attention recently. Unlike the traditional single-input multiple-output (SIMO) radar which emits coherent waveforms to form a focused beam, the MIMO radar can transmit ...

Flexible MIMO arcritectures: guidelines in the design of MIMO parameters
IEEE 6th Workshop on Signal Processing Advances in Wireless Communications, 2005., 2005 One of the multiple advantages of communicating through MIMO systems is their inherent ability to provide flexible configurations. Following this line of thought, in this paper we present a generic framework to study the degrees of freedom in the design of MIMQ communication systems (e.g.: code length, number of multiplexed ...
