摘要

在2ghz频段研究了三元发射(Tx)(基站BS)和四元接收(Rx)(便携式单元PU)天线系统。使用多普勒偏移技术，通过4Rx=12个并行链路同时探测所有3Tx。这允许同时Tx-Rx多样性有效性的调查，以及支持披露并行度(独立通道)。测量主瓣带宽为8mhz。这允许的最大范围约。2.5 km, 0.4 W tx功率和23dbi总天线增益。本文关注的是链路之间的基本权力平衡，这是限制多样性作用和并行性的基本因素。

Measurements of wideband multi-element transmit-receive diversity channels in the UMTS-band

Three element transmit (Tx) (at base station BS) by four element receive (Rx) (at portable unit PU) antenna systems have been investigated at 2 GHz. Simultaneous sounding of all 3Tx by 4Rx=12 parallel links has been performed using a Doppler offset technique. This allows for investigations of simultaneous Tx-Rx diversity effectiveness as well as support for disclosing the degree of parallelism (independent channels). The measurement main-lobe bandwidth is 8 MHz. This allowed a maximum range of approx. 2.5 km with 0.4 W Tx-power and 23 dBi total antenna gain. This paper focuses on the fundamental power balance between links, which is a basic limiting factor for both diversity action and parallelism.
