WebMar 28, 2008 · The union bound on the BEP of the maximum likelihood (ML) decoding is derived for any code rate, unitary space–time constellation and mapping. The tightness of the bound is checked with simulation results of the ordered statistic decoding (OSD). For example, suppose that four numbers are observed or recorded, resulting in a sample of size 4. If the sample values are 6, 9, 3, 8, the order statistics would be denoted where the subscript (i) enclosed in parentheses indicates the ith order statistic of the sample.
