我们报告了我们对具有两个独立发射机的高斯多址信道的容量区域的研究，其中接收机的天线间距非常小（与波长相比）。与普遍看法相反，我们发现即使天线距离接近零，也可以保持矩形容量区域。此外，容量区域的尺寸甚至随着天线间距的减小而增加。因此，在有限空间的情况下，例如在使用标准移动通信频率的手持移动设备中，高性能多址接入是完全可能的。
We report on our investigation of the capacity region of a Gaussian multiple access channel with two independent transmitters for the case where the receiver's antenna spacing is very small (compared to the wavelength). In contrast to common belief, we find that a rectangular capacity region can be maintained even as the distance of the antennas approaches zero. Moreover, the size of the capacity region even increases as the antenna separation is reduced. Therefore, high-performance multiple access is perfectly possible in confined space situations such as in hand-held mobile devices using standard frequencies for mobile communications.
