摘要 该文推导空相关多输入多输出任意衰落参数Nakagami衰落信道上正交空时分组码的香农容量的精确闭合表达式、上限及其在高、低信噪比区域的近似闭合表达式。数值计算结果表明正交空时分组码在空相关多输入多输出Nakagami衰落信道上的香农容量略小于独立衰落信道,同时验证该香农容量在高、低信噪比区域的近似闭合表达式具有较高的准确性。 该文推导空相关多输入多输出任意衰落参数Nakagami衰落信道上正交空时分组码的香农容量的精确闭合表达式、上限及其在高、低信噪比区域的近似闭合表达式。数值计算结果表明正交空时分组码在空相关多输入多输出Nakagami衰落信道上的香农容量略小于独立衰落信道,同时验证该香农容量在高、低信噪比区域的近似闭合表达式具有较高的准确性。
