Abstract: There are few things in nature more unwieldy than the power limited, space varying, time varying, frequency varying wireless channel. Yet there is great reward for engineers who can overcome these limitations and transmit data through such harsh environments. Wireless revenues are growing rapidly per year, which are likely to continue for several years. Wireless system designers are faced with the challenge of meeting the increasing demand for higher data rates, better quality of service, fewer dropped calls, higher network capacity and user coverage calls for innovative techniques that improve spectral efficiency and link reliability. Digital communication using multiple-input—multiple-output (MIMO), sometimes called a "volume-to-volume" wireless link, figures prominently on the list of recent technical advances in the field of modern communications with a chance of resolving the bottleneck of traffic capacity in future internet-intensive wireless networks. MIMO systems can achieve high data rates provided that the multipath scattering is sufficiently high. Solutions that exploit the multipath properly can be captured under the term Space Division Multiplexing (SDM). In this thesis work, the performance evaluation of an SDM technique (VBLAST) is done for MIMO systems. This is then extended to frequency selective cases using the straightforward multicarrier approach, orthogonal frequency division multiplexing (OFDM). Then an iterative detection and decoding (IDD) scheme is considered to improve the performance of VBLAST MIMO OFDM.
