研究了发射分集下无线体域网（WBAN）信道的分集增益和中断容量。通过测量电波暗室中人体运动和发射天线位置对离体信道的影响，研究了人体运动对离体WBAN系统性能的影响。它已被证明，利用两个不相关的信道的发射分集减轻了有害的影响，人类运动的信道条件，并实现高分集增益。
This paper investigates the diversity gains and outage capacities of wireless body area network (WBAN) channels with transmit diversity. The off-body channel in an anechoic chamber, with respect to various human movements and the position of the transmit antennas, are measured to evaluate the influence of the usual body movements on the performance of off-body WBAN systems. It has been demonstrated that transmit diversity exploiting two uncorrelated channels relieves the harmful effect of human movement on the channel conditions and achieves high diversity gains.
