A strategy of radio environments indentifications in software antenna systems
Lanfen Qi · Journal of China Institute of Communications · 2004
Different from smart antenna, software antenna 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, and a spatial smoothing method to realize the identification of radio environment is proposed. Finally, computer simulations under different conditions are demonstrated.
