The Repeater for WCDMA Cellular Mobile Telecommunication Systems
This paper presents the principles and constitutions of RF and fiber optic repeaters to provide wideband code division multiple access(WCDMA) mobile communication services to previous blind areas such as places far away from the city, vast and sparsely populated, inside the buildings or in the underground mall. The thermal noise generated by the repeater increases the uplink noise level and degrades the uplink capacity of a BS(Base Station). In this paper, we analyze the noise floor increase and capacity degradation, as well as propose to select the operation carrier frequency and fix the channel bandwidth to 5MHz by using a surface acoustic wave(SAW) filter to degrade the noise floor in the WCDMA repeater. Finally, it gives some experiment results, and the developed repeater has been used for the WCDMA mobile communication networks in the Hangzhou and Suzhou telecom. of China telecom..
