Since the invention of Information Theory by Shannon in 1948, coding theorists have been working on finding ways to achieve capacity. Recently, two capacity approaching code classes have emerged, namely LDPC and Turbo codes. In this thesis, we focus on LDPC codes. More precisely, we analyse encoding, decoding , design and construction of LDPC codes. The(More)
The combined OFDM/SDMA approach has raised significant research interests recently as it appears to be quite suitable for future broadband wireless transmission. In order to build practical OFDM/SDMA systems, we need to evaluate such systems under real-world conditions. The presence of carrier frequency offsets, caused by inaccuracies of local oscillators(More)
