摘要

由于概率密度函数难以求出，因此对MRC分集接收机在相关衰落信道中的性能研究文献很少。本文表明，利用线性变换技术可以避免这一困难。可以很容易地推导出各种调制方案的平均误码率(SER)的一般封闭表达式。以多电平正交调幅(MQAM)为例，推导了相关衰落信道上的SER。

MRC receiver performance with MQAM in correlated Rician fading channels

Due to difficulties in deriving the probability density function, the performance of the maximal ratio combining (MRC) diversity receiver in correlated Rician fading channels is rarely reported in the literature. This article shows that the difficulty can be avoided by a linear transformation technique. General closed-form expressions of the average symbol error rate (SER) for various modulation schemes can be easily derived. As an example, this paper derives the SER of multilevel quadrature amplitude modulation (MQAM) over correlated Rician fading channels.

期刊介绍： Journal of Signal Processing is an academic journal supervised by China Association for Science and Technology and sponsored by China Institute of Electronics. The journal is an academic journal that reflects the latest research results and technological progress in the field of signal processing and related disciplines. It covers academic papers and review articles on new theories, new ideas, and new technologies in the field of signal processing. The journal aims to provide a platform for academic exchanges for scientific researchers and engineering and technical personnel engaged in basic research and applied research in signal processing, thereby promoting the development of information science and technology. At present, the journal has been included in the three major domestic core journal databases "China Science Citation Database (CSCD), China Science and Technology Core Journals (CSTPCD), Chinese Core Journals Overview" and Coaj. It is also included in many foreign databases such as Scopus, CSA, EBSCO host, INSPEC, JST, etc.
