Abstract: PROBLEM TO BE SOLVED: To provide a reconstructable base station capable of supporting many communication references in a CDMA radio system. SOLUTION: This reconstructable base station suitable to support many radio communication system references includes the set of a channel unit board, the set of a radio board and a reconstructable bus that mutually connects the channel unit board and the radio board. The base station is constructed so as to support a specific radio system reference such as IS-95 CDMA. The base station can reconstruct an orthogonal transmission diversity(OTD) so as to support other CDMA references such as an IS-95C, a multi-carrier(MC) cdma 2000 or a universal mobile telecommunication system(UMTS). The allocation of a signal line can dynamically be carried out by establishing a fixed connection among a bus signal line and the channel unit and the port of the radio board.
