Design of high-speed modem in drilling rescue
In view of problem of low communication rate of armored cable which is used as communication line in drilling rescue, the paper designed a high-speed modem. The modem takes DSP chip TMS320F2812 as core, combines with programmable logic device FPGA to realize signal sampling and capture, and carrier...

| description | In view of problem of low communication rate of armored cable which is used as communication line in drilling rescue, the paper designed a high-speed modem. The modem takes DSP chip TMS320F2812 as core, combines with programmable logic device FPGA to realize signal sampling and capture, and carrier modulation and demodulation are conducted on baseband signal by use of amplitude shift keying mode. The test result shows that the high-speed modem can improve transmission rate of signal and anti-interference ability effectively in 1 000 m rescue communication line, and data transmission rate is higher than 1 Mbit/s. |
