Due to the enormous performance enhancement, multi-antenna systems have arrest large attention. The well known BLAST system (Bell-Labs Layered Space-Time) is one very intresting approach to use multiple antennas for increasing the data rate. Thereby the transmitter demultiplexes the information data in so called layers (substreams) and simultaniously transmit them over the several antennas. The receiver uses a successive detection algorithm to optain the information data, which however assumes a non-frequency-selective fading channel.

For the detection of BLAST systems in frequency-selective environments several techniques have been recently proposed. In this thesis the so called MIMO Turbo-Equalizer should be investigated. This scheme iteratively applies linear equalization and channel decoding in terms of turbo decoding. The fundamental theory of this architecture should be investigated and has to be realized in MATLAB. With respect to simulation results the performance has to be compared with other detection schemes. The adaptation of this thesis presumes knowledge in the field channel coding.
