| In this paper, a PCM telemetry synchronization decoder is designed. A strategy for capturing the PCM telemetry data of transient process from the continuous PCM stream with buffer RAM is presented. The FPGA is used to complete the bit synchronizer and the frame synchronizer. The whole telemetry decoder is embedded in a PC card, which is used for decoding 4Mbps-bit rate. The virtual instrument(VI)soft panel is programmed by using Labwindows/CVI to achieve the control of the hardware and the display, processing, restoring of the decoded multi-channel data. |
