CDMA (Code Division Multiple Access) system has great operating prospects, in the third generation of mobile communication development process, the network competitiveness, network operation quality put forward higher requirements. This paper first introduces the self-interference characteristic of CDMA network, first introduces the concept of pilot pollution for CDMA network. Secondly, from the causes of high-level pilot pollution problems, the solution of high-level pilot pollution concentration is put forward for different situations. Finally, the problem of high-level pilot pollution is further analyzed with practical examples.<\/p>","DOI":"10.4018\/ijapuc.2016070103","type":"journal-article","created":{"date-parts":[[2017,1,30]],"date-time":"2017-01-30T14:30:23Z","timestamp":1485786623000},"page":"87-128","source":"Crossref","is-referenced-by-count":0,"title":["Monitoring and Optimization of Pilot Pollution in High-Rise"],"prefix":"10.4018","volume":"8","author":[{"given":"Tianze","family":"Li","sequence":"first","affiliation":[{"name":"Udutech, Inc., Shijiazhuang, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6998-7654","authenticated-orcid":true,"given":"Tao","family":"Gao","sequence":"additional","affiliation":[{"name":"Department of Automation, North China Electric Power University, Baoding, China"}]},{"given":"Ye","family":"Liu","sequence":"additional","affiliation":[{"name":"Udutech, Inc., Shijiazhuang, China"}]},{"given":"Yuhan","family":"Wang","sequence":"additional","affiliation":[{"name":"Southeast University, Nanjing, China"}]},{"given":"JiaHui","family":"Chen","sequence":"additional","affiliation":[{"name":"Beijing University of Posts and Telecommunications, Beijing, China"}]}],"member":"2432","reference":[{"key":"IJAPUC.2016070103-0","unstructured":"Ashikhmin, A., Marzetta, T.L., & Jose, J.
