Multiple-Input Multiple-Output (MIMO) wireless communication system, which is also called Multiple-Antenna system, is well known as one of the most important technologies and widely studied nowadays (Winters, 1987; Foschini & Gans, 1998; Marzetta & Hochwald, 1999; Raleigh & Cioffi, 1998). The main idea of MIMO wireless communication is to utilize the spatial degree of freedom of the wireless mu...

Abstract – The use of Rake Receiver in Wideband Code Division Multiple Access (WCDMA) system provides a unique and valuable means of combating the adverse effects of short-term multipath fading in mobile radio propagation environments. The transmitted signal bandwidth in WCDMA system is much larger than the coherent bandwidth of the channel, in this case the channel is frequency selective chann...

In this work, we consider the use of multiple antenna signaling technologies, specifically space-time block coding (STBC) and spatial multiplexing (SM) schemes, in multiple-input multiple-output (MIMO) communication systems employing dual polarized antennas at both ends. The use of dual-polarized antennas theoretically double the number of virtual antennas used in the system. On the other hand,...

Employing multiple antennas at both the transmitter and the receiver linearly boosts the channel capacity by min (nT , nR), where nT and nR are the number of transmit and receive antennas, respectively A. Telatar (1999). Multiple-Input Multiple-Output (MIMO) technologies are classified into three categories: (i) MIMO diversity, (ii) MIMO Spatial Multiplexing (MIMO-SM) and (iii) beamforming that...

The use of spatial multiplexing (SM) in multiple-input multiple-output (MIMO) wireless systems promises a linear (in the minimum of the number of transmit and receive antennas) increase in data rate. In practice, the performance of SM depends critically on a variety of channel conditions including antenna height and spacing, polarization of antennas, and richness of scattering. Transmit correla...

This paper addresses the problem of MIMO spatialmultiplexing (SM) systems in the presence of antenna fading correlation. Existing SM (V-BLAST and related) schemes rely on the linear independence of transmit antenna channel responses for stream separation and suffer considerably from high levels of fading correlation. As a result such algorithms simply fail to extract the non-zero capacity prese...

In this paper, a transmitter-based multipath processing and inter-channel interference (ICI) cancellation scheme for a ultra-wideband (UWB) spatial multiplexing (SM) multiple input multiple output (MIMO) system is presented. It consists of taps delayed lines and zero-forcing (ZF) filters in the transmitter and correlators in the receiver. For a UWB SM MIMO system with N transmit antennas, M rec...

During the last decade, multiple-input multiple-output (MIMO) systems, where both the transmitter and receiver are equipped with multiple antennas, have been verified to be a very promising technique to break the throughput bottleneck in future wireless communication networks. Based on countless results of analysis and field measurements that have been undertaken by many researchers around the ...
