We present a new space-time encoderbased on packet-level redundancy which can increase the space-time encoder rate beyond unity without compromising diversitygains. A complementary low-complexity decoding algorithmbased on maximum ratio combining and successive interferencecancelation is further proposed. A major merit of the decodingalgorithm is that it allows to adaptively tradeoff betweendiversity and multiplexing gains based on the estimated channelparameters at the receiver without requiring any channel stateinformation at the transmitter. System level simulation resultsgive insight into the advantages of the proposed scheme whencompared to its Alamouti and MIMO multiplexing based onsingle value decomposition counterparts.
