This paper discusses the packet error rate (PER) performance of multiple-input multiple-output (MIMO) wireless systems. We focus our discussion on communication systems based on the IEEE 802.11a/g standard. In particular, we study the performance of

Multi-antenna techniques offers significant capacity benefits. But realizing these gains in practical wireless systems remains a very challenging problem. MIMO-OFDM has been used in wireless LAN systems with great success. However, due to the largely

The preamble design for a highly flexible wireless communication system can be challenging. This paper describes a preamble design for ultra mobile broadband (UMB) communication systems that allows flexible deployment, such as flexible bandwidth allo

We derive an approximate ergodic capacity expression for high K-factor Rician channels, where the channel mean is of any rank and the fading channel components are correlated. We propose two sub-optimal linear pre-coding schemes that can improve the

The paper discusses antenna subset selection in MIMO wireless systems. The subsets of transmit and receive antennas are selected so as to maximise the channel capacity. First of all, we establish the relationship between the multiplexing gain and the

In this paper, we discuss the performance of MIMO spatial multiplexing (MIMO-SM) systems. The first part compares the performance of the ordered successive cancellation (OSIC) receiver, with independent encoding per antenna at the transmitter, with t

The authors recently introduced a novel approach for detection-estimation of more uncorrelated Gaussian sources than sensors in sparse linear antenna arrays that is critically dependent on accurate likelihood-ratio (LR) maximisation over the set of c

The use of multiple element antennas (MEA) at the transmitter and receiver offers a possibility to substantially increase the throughput of a fading channel. Recent publications show that for a moderate number of transmit/receive subchannels, the out
