正交空时分组码译码的计算复杂性

Computational Complexity of Decoding Orthogonal Space-Time Block Codes

Ender Ayanoglu, Erik G. Larsson, Eleftherios Karipidis

摘要:

量化了正交空时分组码G的最优译码的计算复杂性,该正交空时分组码G满足正交性,即G乘以G的Hermitian转置等于常数c乘以码的平方符号之和乘以单位矩阵,其中c为正整数。文中给出了四种具有相同计算复杂性的最佳译码等价技术。在特殊情况下的基本配方的修改计算和举例说明。本文修正和推广了[1]、[2],并将它们与文献中的结果统一起来。此外,文献中的一些结果也推广到了c > 1的情形.

英文摘要:

The computational complexity of optimum decoding for an orthogonal space-time block code G satisfying the orthogonality property that the Hermitian transpose of G multiplied by G is equal to a constant c times the sum of the squared symbols of the code times an identity matrix, where c is a positive integer is quantified. Four equivalent techniques of optimum decoding which have the same computational complexity are specified. Modifications to the basic formulation in special cases are calculated and illustrated by means of examples. This paper corrects and extends [1],[2], and unifies them with the results from the literature. In addition, a number of results from the literature are extended to the case c > 1.
