| Summary: | We present a new space-time encoder
based on packet-level redundancy which can increase the space-time encoder rate beyond unity without compromising diversity
gains. A complementary low-complexity decoding algorithm
based on maximum ratio combining and successive interference
cancelation is further proposed. A major merit of the decoding
algorithm is that it allows to adaptively tradeoff between
diversity and multiplexing gains based on the estimated channel
parameters at the receiver without requiring any channel state
information at the transmitter. System level simulation results
give insight into the advantages of the proposed scheme when
compared to its Alamouti and MIMO multiplexing based on
single value decomposition counterparts. |
