摘要

在28ghz频段采用大规模多输入多输出(MIMO)导频模式，研究在非完美信道状态信息(CSI)知识假设下，嵌入式交换技术的误码率(BER)性能。对比分集和空间复用，研究了嵌入式交换技术的误码率性能。因此，在非完美CSI知识假设下，与空间复用和分集相比，嵌入式开关技术在BER=10−3时的信噪比提高了2.5 dB。此外，它对信道估计误差具有鲁棒性。

Embedded switching technique in a realistic 28 GHz system

This paper aims to investigate the Bit Error Rate (BER) performances of the embedded switching technique under the assumption of non-perfect Channel State Information (CSI) knowledge using a Massive Multiple-Input Multiple-Output (MIMO) pilot pattern in the 28 GHz band. It studies the BER performances of the embedded switching technique compared to diversity and spatial multiplexing. As a result, the embedded switching technique offers an improvement of 2.5 dB in the signal-to-noise ratio at BER=10−3compared to spatial multiplexing and diversity under the assumption of non-perfect CSI knowledge. Moreover, it is robust against channel estimation errors.
