| Abstract(in English) | This paper presents fully digital high speed (17.6Mbps) burst modem for Offset Quadrature Phase Shift Keying (OQPSK), which employs novel digital modem VLSICs. The modulator VLSIC directly generates modulated IF signals in a fully digitalized manner. The demodulator VLSIC achieves fast carrier and bit-timing acquisition in burst mode by employing novel carrier/bit timing recovery schemes. It also supports stable initial burst acquisition by a digital burst detector and a novel Automatic Frequency Control (AFC) acquisition detector. Performance evaluation results show that the new modem achieves satisfactory bit-error-rate performance in severe environments. The developed modem has been employed in a commercial satellite communication system and reduces the hardware size to one third that of the conventional one. |
