Abstract
An antenna selection decision system detects the level of the TDM burst immediately preceding to the TDM
burst of the user's own channel and decides, on the basis of the detected level, to use the antenna selection diversity method or another selection criterion. When the other selection criterion is selected, the antenna which should receive the next TDM burst of the user's own channel is selected depending on the level of TDM burst of the user's own channel.
