Multimode software radio system by parameter controlled and telecommunication component block embedded digital signal processing hardware

In this paper, a new configuration method of multimode software radio syste m by parameter controlled and tt telecommunication component block embedded digital signal processing hardware (DSPH) is proposed fur the future flexi ble multimedia communications. In this method, in advance, basic telecommun ication component blocks are implemented in the DSPH like DSF and FPGA. And , external parameters, which are simple but important information, change t he specification of each block. Tills proposed method has: the following fe atures: i) People need to have only one mobile handset and select communica tion services as they like. ii) The volume of download software is reduced drastically in comparison with conventional full-download-type software rad io system. iii) Since important component blocks have already been implemen ted into the DSPH except for some external parameters in advance, the know- how related to the implementation of DSPH never leak out. In this paper, we evaluate the effectiveness of the proposed configuration method by using c omputer simulation and developed experimental prototype and comparing with full-download-type software radio system from the viewpoint of the volume o f download software. Finally, we introduce several new software radio syste ms by using tho proposed configuration method.
