Abstract :
An astonishing difference in the performance of non-orthogonal space-time block codes (NOSTBCs) on wireless multiple-input/multiple-output (MIMO) systems compared to one-dimensional block codes operating on single-input/single-output (SISO) channels is derived. Using NOSTBCs, single symbol errors are no longer the only dominating error types, but multiple symbol errors can dominate the error performance in the high SNR range.
