Abstract: PROBLEM TO BE SOLVED: To utilize circuit components between both low-speed high-speed systems by generating two component CDMA data signals or more with respect to each user data signal received by a high-speed data processor and generating a low-speed CDMA channel signal, with respect to at least one user data signal received by a 1ow-speed CDMA processor. SOLUTION: A transmission section of a base station includes two separate RF processing parts. For example, the transmitter includes a low-speed digital signal processing block 602 and a CDMA radio circuit 604 for, e.g. an IS-95 signal processing. The system includes also a narrow band RF amplifier 606 and a transmission filter XMT 608 in a 1st path, and also a high speed broadband CDMA digital signal processing block 612 that processes a signal in compliance with the broadband CDMA standard, a broadband CDMA radio circuit 614, an RF amplifier 616 and a transmission filter XMT 618 in a 2nd path. So long as the processing in both the paths is conducted separately, a signal in compliance with both the standards is outputted to an antenna 610.

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.
