SIMO预日志可以大于SISO预日志

The SIMO Pre-Log Can Be Larger Than the SISO Pre-Log

Veniamin I. Morgenshtern, Giuseppe Durisi, Helmut Bölcskei

摘要:

我们建立了一个时间相关的瑞利块衰落单输入多输出(SIMO)信道的非相干容量pre-log的下界。令人惊讶的是,当信道的协方差矩阵满足与其最小线性相关行集合的基数相关的特定技术条件时,该下限揭示了SIMO情况下的容量预对数大于单输入单输出(SISO)情况下的容量预对数。

英文摘要:

We establish a lower bound on the noncoherent capacity pre-log of a temporally correlated Rayleigh block-fading single-input multiple-output (SIMO) channel. Surprisingly, when the covariance matrix of the channel satisfies a certain technical condition related to the cardinality of its smallest set of linearly dependent rows, this lower bound reveals that the capacity pre-log in the SIMO case is larger than that in the single-input single-output (SISO) case.
