Base station cooperation is a promising technique to address the serious co-channel interference issue, but dramatic signaling overhead and high computational complexity are inherent in this advanced coordination technology. Limited form of cooperation among base stations becomes an practical method to deploy this multiple cell processing in a realistic network. After analyzing the multi-cell sum...
Civil aviation develops rapidly, to enhance the security and reliability of instrument landing system, adaptive beamforming technology has been proposed to the future air traffic control system, which is a cooperative instrument landing system. Based on adaptive beamforming technology, the feasibility was analyzed in this work. Adaptive signal equations were deduced in adaptive instrument landing...
In WCDMA uplink, there are I/Q and code division multiplexed dedicated physics control channel (DPCCH) and dedicated physical data channel (DPDCH). And in DPCCH there are connection dedicated pilot sequences. This paper introduces two new adaptive algorithms for smart antenna processing in such CDMA systems, which can efficiently exploit the special signal transmitting structure. The main feature...
