Bibliography:A method to lossless compress multi-channel noise data is proposed by using DSP＋FPGA architecture and ARC algorithm.Detailed explanations of the key technologies such as analog to digital conversion,the design of data buffer and how program run in DSP are given.Using a test platform to verify the performance of this design,the results show that the consequent of noise data compression is obviously,the reduction of noise signal is perfect.Thus it realizes lossless compression of noise data and can well meet the needs of the telemetry system.
