Description: ns STBC for purely time-selective channels by transforming the
time-selective channels into frequency-selective channels, and by
adjusting existing space–time code designs over frequency-selective
MIMO channels to collect joint space–Doppler gains over purely
time-selective MIMO channels. Further, [14] uses the ideas of [12] to
develop a space–time code that can achieve full space-delay-Doppler
diversity for any number of transmit–receive antennas. However, to
quantify the maximum Doppler diversity order [2], the above papers
rely on a parsimonious critically sampled complex-exponential basis
expansion model (CCE-BEM) for the underlying purely time-selective
or doubly-selective channels [16]. However, the CCE-BEM may have
a large modeling error under certain channel conditions Platform: |

Description: MIMO-OFDM is a key technology for next-generation cellular communications (3GPP-LTE,
Mobile WiMAX, IMT-Advanced) as well as wireless LAN (IEEE 802.11a, IEEE 802.11n),
wireless PAN (MB-OFDM), and broadcasting (DAB, DVB, DMB). This book provides a
comprehensive introduction to the basic theory and practice of wireless channel modeling,
OFDM, and MIMO, with MATLAB programs to simulate the underlying techniques on
MIMO-OFDM systems. This book is primarily designed for engineers and researchers who are
interested in learning various MIMO-OFDM techniques and applying them to wireless
communications. It can also be used as a textbook for graduate courses or senior-level
undergraduate courses on advanced digital communications. The readers are assumed to have
a basic knowledge on digital communications, digital signal processing, communication
theory, signals and systems, as well as probability and random processes. Platform: |
