Orthogonal space-time block codes (OSTBC) are attractive in that they can achieve full diversity and linear complexity of maximum likelihood (ML) decoding. However, the OSTBC have a low symbol rate due to the limitation of the orthogonality of the code structure. Most of the high-rate STBC achieve full diversity based on ML decoding at the receiver that is computationally expensive. In order to achieve...
Recently, orthogonal frequency division multiplexing (OFDM) has become a popular technique for transmission of signals over wireless channels. Also, multiple-input multiple-output (MIMO) is one of the most promising technologies for assisting fading and improving link reliability without sacrificing bandwidth efficiency. The combination of OFDM and MIMO seems to be the key technology in next generation...
