Classification and identification of radio environments in software antenna
Ping Tan · Chinese Journal of Radio Science · 2003
Based on the smart antenna technology, a new concept of software antenna has been proposed recently. It can recognize the status of the radio environments and appropriately select an algorithm to dynamically reconfigure itself by the recognized environment. One of the key technologies to realize software antenna is the classification and identification of the radio environments. In this paper, we discuss the categorization of the radio environments and the criteria of identification in CDMA systems Finally a spatial smoothing method to realize the identification of radio environment is proposed. Simulations have been conducted which demonstrated the effectiveness of this approach.
