摘要: Ray tracing has been extensively used to simulate indoor channel characteristics. For an ultra-wideband system, the characteristics vary significantly over entire bandwidth. To cope with this, sub-band divided RT proposed by dividing frequency of interest into multiple subbands and superposing results at individual center each subband. Thus, computational complexity is directly proportional number subbands. In this paper, we propose a mathematical method reduce RT, making it almost independent It important note that, based on our approach, not only determination rays reaching give location made once, but also electromagnetic calculation received signal needed perform repeatedly. The accuracy low-complexity subband algorithm verified through measurement campaign.
