This paper proposes a novel iterative multiple-input multiple-output (MIMO) receiver for orthogonal frequency division multiplexing (OFDM) systems, named as an “iterative MIMO receiver employing virtual channels with a Turbo decoder.” The proposed MIMO receiver comprises a MIMO detector with virtual channel detection and a Turbo decoder, between which signals are exchanged iteratively. This pap...

In this paper, a Gaussian multiple input multiple output multiple eavesdropper (MIMOME) channel is considered where a transmitter communicates to a receiver in the presence of an eavesdropper. We present a technique for determining the secrecy capacity of the multiple input multiple output (MIMO) channel under Gaussian noise. We transform the degraded MIMOME channel into multiple single input m...

This paper compares the packet error rate (PER) performance of several transmit/receive architectures for multiple-input multiple-output (MIMO) wireless systems. We focus our study on systems based on the IEEE 802.11a/g standard. Spatial multiplexing architectures like minimum mean square error (MMSE) detection with joint encoding at the transmitter are compared to diversity architectures based...

The capacity of multiple input, multiple output (MIMO) wireless channels is computed for Ricean channels. The novelty is a geometrical (ray-tracing) interpretation of the MIMO channel capacity formula to find array geometries which greatly enhance channel capacity compared to single input–single output (SISO) systems.

With the development of an electronic interference technique, self-defense jammer can generate mainlobe jamming using range gate pull-off (RGPO) strategy, which brings serious performance degradation target tracking for ground-based warning radar. In this paper, a RGPO suppression approach is proposed, with frequency diverse array multiple-input multiple-output (FDA-MIMO) The differs from true ...

We propose a new scheme to estimate the directions-of-arrival (DOAs) of mixed coherent and uncorrelated targets exploiting a collocated multiple-input multiple-output (MIMO) radar with transmit/receive coprime arrays. In the proposed scheme, the DOAs of the uncorrelated targets are first estimated using subspace-based methods, whereas those of the coherent targets are resolved using Bayesian co...

Through-wall-radar imaging is of interest for mapping the wall layout of buildings and for the detection of stationary targets within buildings. In this paper, we present an easy single-side two-location spotlight imaging method for both wall layout mapping and stationary target detection by utilizing multiple-input multiple-output (MIMO) through-wall-radar. Rather than imaging for building wal...
