ABSTRACT
Multipath signal propagation is the defining characteristic of terrestrial
wireless channels. Virtually all existing statistical models for
wireless channels are implicitly based on the assumption of rich
multipath, which can be traced back to the seminal works of Bello
and Kennedy on the wide-sense stationary unco ....etc

We present a new model for multiple input multiple-output (MIMO) out door wireless fading channels which is more general and realistic than the usual i.i.d. model. We investigate the channel capacity as a function of parameters such as the local scattering radius at the transmitter and the receiver, the distance between the transmit (TX) and receive (RX) arrays, and the antenna beamwidth sand spacing. We point out the existence of pinhole channels which exhibit low fading correlation between antennas but still have poor rank properties and hen ....etc

MIMO Wireless Channels: Capacity and Performance Prediction


Multiple-input multiple-output (MIMO) communication techniques make use of multi-element antenna arrays at both the TX and the RX side of a radio page link and have been shown theoretically to drastically improve the capacity over more traditional single-input multiple output (SIMO) systems . SIMO channels in wireless networks can provide diversity gain, array gain, and interference canceling gain among other benets. In addition to these same advantages, MIMO links can ....etc

Introduction

OFDM: a form of MultiCarrier Modulation.
Different symbols are transmitted over different subcarriers
Spectra overlap, but signals are orthogonal.
Example: Rectangular waveform -> Sinc spectrum

Abstract

Wireless technology has become the most exciting area in telecommunication and networking. The rapid growth of mobile telephone use, various satellite services, and now the wireless Internet are generating tremendous changes in telecommunications and networking. Wireless is convenient and often less expensive to deploy than fixed service, but wireless is not perfect. There are limitations, political and technical difficulties that may ultimately prevent wireless technologies from reaching their full potential. Regardless of t ....etc
