Field test of HTS receivers on CDMA demonstration cluster in China
Keywords: HTS filter,demonstration cluster,HTS receiver,CDMA,field test Abstract: This paper presents the field test of our first demonstration cluster with five base stations (BTS) on code division multiple access (CDMA) wireless communication in China, while each BTS was installed with a high temperature superconductor (HTS) receiver. The HTS receivers have the same centre frequency of 830 MHz, a bandwidth of 13 MHz, and a noise figure (NF) of 0.9 dB. After the conventional receivers in the BTSs were replaced by the HTS receivers, a consequent drive test was carried out. A 2.35 dB decrease of the mean mobile transmit power was observed in the demonstration cluster. Supported by the National Natural Science Foundation of China (Grant No. 60471001)
