摘要

在接收机中，智商失衡对数据传输性能有显著影响。比较了不同类型的正交空时分组码在智商不平衡情况下的性能，发现不同的码并不具有相同的行为。尽管大多数代码在低不平衡情况下具有可接受的性能，但它们在存在大量非理想情况时仍能正常工作。尽管有这种总体上的相似性，但在针对非理想性的行为中，这些规范存在一些差异。这种差异使它们适用于不同的情况。

Performance comparison of different STBC codes in the presence of IQ imbalances in mobile communications

In receivers, IQ imbalances have significant effects on the performance of data transmission. Comparison of the performance of different types of orthogonal space-time block codes (OSTBC) in the presence of IQ imbalances show that different codes donpsilat have a same behavior. Although most codes have an acceptable performance in low imbalances, they canpsilat work properly in the presence of intensive non-idealities. Despite this general similarity, there are some differences in the behavior of the codes against non-idealities. Such differences make them suitable for different situations.
