Geng, Jian and Pan, Chengkang and Huang, Fan and Xiang, Wei and Wang, Qixing and Guangyi, Liu and Xiaodong, Shen and Yang, Dacheng (2011) Antenna gain mismatch calibration for cooperative base stations. In: 2011 IEEE Vehicular Technology Conference: Smarter Communication for an Intelligent World (VTC 2011-Fall), 5-8 Sep 2011, San Francisco, CA, United States.
In real environments, channel reciprocity cannot be directly exploited between uplink and downlink in time division duplex (TDD) due to antenna gain mismatch. Previous work about antenna calibration mainly focused on single cell. This work proposes an adaptive scheme for antenna calibration between two cooperative BSs. The proposed scheme aims at achieving an equal ratio between antenna transmitter and receiver analog gains among cooperative BSs in flat fading channels. The essential idea is to relay calibration parameter through a calibration path. This procedure can be controlled by a certain BS dubbed primary BS. Evaluation of the proposed scheme is carried out by computer simulation.
