求翻译：UWB系统性能受信道传播和多径的影响很大，需要对UWB传播环境进行深入研究以更精确地预测UWB系统性能和优化收发信机设计。是什么意思？

uwb system performance by channel propagation and multipath a great influence on uwb propagation environment in-depth study in order to more accurately predict the uwb system performance and optimize the transceiver design.

UWB system performance can be affected by channel communications and multi-path of a very large impact, you need to disseminate environmental UWB for in-depth research to more accurately forecast UWB System Performance and Optimization transceiver design.

The UWB system performance is very big the channel dissemination and the multi-diameter influence, needs to conduct the thorough research to the UWB dissemination environment by to forecast the UWB system performance and the optimized receiver transmitter design precisely.

UWB systems performance effect and multipath channel propagation is very large, require in-depth study on UWB transmission environment to more accurately predict UWB transceiver design and optimization of system performance.
