先前的结果在任意相关衰落信道的分集接收的准确的错误率和中断概率涉及棘手的嵌套积分，这使得性能分析具有挑战性的进行。在本文中，我们推导出渐近表达式和渐近紧界的错误率和中断概率的分集接收（包括最大比合并，选择合并，等增益合并）在任意相关的贝克曼衰落信道。这些新的渐近性能表达式揭示了任意相关贝克曼衰落信道的分集系统的见解，和渐近性能表达式的准确性明确量化的性能界限。使用这些分析工具，可以评估的分集接收系统的性能在任意相关的贝克曼衰落信道，而不诉诸耗时的蒙特卡罗模拟或数值多重积分。
Prior results on exact error rates and outage probabilities of diversity receptions over arbitrarily correlated fading channels involve intractable nested integrals, which makes the performance analyses challenging to carry out. In this paper, we derive asymptotic expressions and asymptotically tight bounds for error rates and outage probabilities of diversity receptions (including maximal-ratio combining, selection combining, and equal-gain combining) over arbitrarily correlated Beckmann fading channels. These new asymptotic performance expressions reveal insights into the diversity systems over arbitrarily correlated Beckmann fading channels, and the accuracy of the asymptotic performance expressions is explicitly quantified by the performance bounds. Using these analytical tools, one can assess the performance of the diversity reception systems over arbitrarily correlated Beckmann fading channels without resorting to time-consuming Monte Carlo simulation or numerical multifold integration.
