Description: The main goal of this work is to provide a unified theory of QSTBCs for four transmit antennas and
one (or more) receive antennas. The thesis consists of two main parts: In the first part we analyze the
QSTBCs transmission without any channel knowledge at the transmitter and in the second part we analyze
transmission with QSTBCs assuming partial channel state (CSI) information at the transmitter.
For both cases, the QSTBCs are studied on spatially correlated and uncorrelated frequency flat MIMO
channels applying a Maximum Likelihood receivers as well as a low complexity linear Zero-Forcing
receivers. The spatial correlation is modelled by the so-called Kronecker Model. Measured indoor channels
are also used in our simulations to show the performance of the QSTBCs in real-world environment

Description: This examples corresponds to a 2x2 system with parallel linear arrays, where the mobile moves aways from the base station,
with a constant speed such that the Maximum Doppler frequency is 5 Hz. The element spacings at the base station and mobile are one lambda and 0.5 lambda, respectively. The maximum angle spread at the base station is 4 degrees, whereas isotropic scattering is assumed around the mobile. The length of the simulated MIMO channel is 5 seconds, and any two adjacent samples are spaced by 0.01 seconds. For ensemble averaging, 90 realizations of the MIMO channel are generated.-This examples corresponds to a 2x2 system with parallel linear arrays, where the mobile moves aways from the base station, with a constant speed such that the Maximum Doppler frequency is 5 Hz.

Description: Iterative receiver techniques, multiple-input – multiple-output (MIMO) processing, and
orthogonal frequency division multiplexing (OFDM) are amongst the key physical layer
technologies when aiming at higher spectral efficiency for a wireless communication system.
Special focus is put on iterative detection, decoding, and channel estimation for a MIMO-OFDM
system. After designing separately efficient algorithms for the detection, channel decoding, and
channel estimation, the objective is to optimize them to work together through optimizing the
activation schedules for soft-in soft-out (SfISfO) components.

Description: As a multi-carrier modulation scheme, Orthogonal Frequency Division Multiplexing (OFDM)
technique can achieve high data rate in frequency-selective fading channels by splitting a
broadband signal into a number of narrowband signals over a number of subcarriers, where
each subcarrier is more robust to multipath. The wireless communication system with multiple
antennas at both the transmitter and receiver, known as multiple-input multiple-output
(MIMO) system, achieves high capacity by transmitting independent information over different
antennas simultaneously. The combination of OFDM with multiple antennas has been
considered as one of most promising techniques for future wireless communication systems.
