| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper describes an evaluation of an RF signal Direct-Processing Receiver that samples the RF signal directly and makes signal process without frequency conversion parts for the purpose of smaller and more efficient of the Reconfigurable Communication Equipment on SmartSat-1. This Receiver has a demodulation part and a modulation part for evaluation of 100 Mbps and the QPSK, and can receive L band RF signals using direct undersampling technology by fsample of 1.5 GHz with no IF signal processing. It was substantiated that this RF direct receiver makes possible drastic scale reduction of the device complexity while keeping equal performance with the existing method by a sampling and a direct output of L band frequency simultaneously and inserting an equalizer designed considering linear amplitude distortion by the sampling frequency response in L band. | |
