Abstract(in English) | Voice service is currently the main service in mobile satellite communications, but in the futute, there will be a demand for high-data rate services offering multimedia contents.Therefore, an onboard processor capable of handling services of various data rates is required.In the present study, it is assumed that a non-regenerative onboard processor will be used.The onboard processor must have functions to filter signals and convert their frequencies in a channel-by-channel manner.An FFT filter bank satisfies these requirements.However, the conventional onboard FFT filter bank is only applicable to signals of constant bit rate.Hence, the onboard bandwidth-variable filter bank that can handle many signals of various bit rates is proposed.The principle of operation of the bandwidth-variable FFT filter bank is described, then the BER performance of an FPGA-implemented design is evaluated. |
