Abstract:Alamouti code with differential encoding has been recently proposed for OFDM systems. It allows full-rate and full-diversity communication and can be decoded with a linear complexity when using two transmit and one receive antennas. However, these advantages assume no interbloc interference (IBI) and no intersymbol interference (ISI) which occur only if the Guard Interval (GI) size is larger than the channel length. In order to relax this condition and to increase the effective flow, we adopt firstly linear ch… Show more
