This paper presents the capacity performance of multiple antennas for wireless communication systems. Multiple antennas structures can be classified into single-input multiple-outputs (SIMO), multiple-inputs single output (MISO), and multiple-inputs multiple-outputs (MIMO) systems. Assuming that the channel is unknown at receiver, capacity expressions are provided for each structure. Our result...

The transmit array of multi-overlapped-transmit-subarray configured bistatic multiple-input multiple-output (MOTS MIMO) radar is partitioned into a number of overlapped subarrays, which is different from the traditional bistatic MIMO radar. In this paper, a new unitary ESPRIT scheme for joint estimation of the direction of departure (DOD) and the direction of arrival (DOA) for MOTS MIMO radar i...

In this paper, we consider the problem of multiple-input multiple-output (MIMO) radars employing the generalized detector (GD) based on the generalized approach to signal processing in noise (GASP) and using the space-time coding to achieve a desired diversity. To that end, we derive a suitable GD structure after briefly outlining the model of the received target return signal. GD performance i...

The use of Multiple-Input Multiple-Output (MIMO) channels has recently attracted considerable interest as an approach that can yield significant capacity gains over conventional smart antenna arrays. This paper presents a new channel model for MIMO systems in populated indoor environments. The model is based on geometrical optics and a detailed radar cross-section (RCS) representation of the hu...

The simultaneous multi-beam working mode of the collocated multiple-input and multiple-output (MIMO) radar enables to track multiple targets simultaneously. A joint power bandwidth allocation algorithm in a MIMO based on quality service (QoS) framework is proposed for multi-target tracking problem with different threat levels. Firstly, posterior Cramer–Rao lower bound (PCRLB) concerning derived...

Introducing frequency agility into a distributed multiple-input multiple-output (MIMO) radar can significantly enhance its anti-jamming ability. However, it would cause the sidelobe pedestal problem in multi-target parameter estimation. Sparse recovery is an effective way to address this problem, but cannot be directly utilized for estimation frequency-agile MIMO radars due spatial diversity. I...

Future Wireless Networks are expected to adopt multi-user multiple input multiple output (MU-MIMO) systems whose performance is maximized by making use of precoding at the transmitter. This chapter describes the recent advances in precoding design for MU-MIMO and introduces a new technique to improve the precoder performance. Without claiming to be comprehensive, the chapter gives deep introduc...

In a multiple-input, multiple-output (MIMO) radar system, two or more transmitters emit independent waveforms, with the resulting reflections received by an array of receivers. Recently, MIMO radar has become a subject of great interest. In part, this interest is due to the potential for MIMO techniques to reduce radar weight and cost, while maintaining performance (as compared with conventiona...

In this paper, novel Dual-Functional Radar-Communication (DFRC) waveforms with peak average power ratio (PAPR) constraint are designed, which under the multiple-input multiple-output (MIMO) radar-communication system. The DFRC transmitted by multiple antennas can send communication information to many downlink cellular users and detect radar targets simultaneously. An optimization model is esta...
