  1. Ab stract the author is engaged in the studying and manufacturing of an intelligent, capable and portable, multifuctional electrocardio monitoring equipment with aduc8 12 single - chip. microcomputer. the equipment can gather and record the electrocardio signals automatically, also can analyse it at real time, and send it out to the monitoring center through the telephone at real time or send it out by serial interfaces to computer. it use the graph display device to show the electrocardio waves and menu. cooperated with buttons, it provides amicable interface, and makes operation simple and convenient. based on the feature of the electrocardio signals, this paper also proposes a electrocardio distortionless data compression algorithm. the algorithn is simple but effective, it can process the data at real time, and the compression - ratio reaches 2 6

    所研製的監護儀能長時間採集和記錄心電信號，同時可進行心電數據的實時分析，並可通過電話向監護中心實時發送，也可通過串列介面發送至微機。該監護儀採用圖形液晶顯示器顯示心電波形和菜單，配合按鍵提供友好的人機界面，操作簡潔。本文還根據心電波形的特徵，提出一種心電數據的無損壓縮演算法，該演算法簡單有效，能實時實現，壓縮比達到2 6倍。
  2. Firstly, based on conventional vq, a fast algorithm named equal - sum block - extending nearest neighbor search ( ebnns ) is presented, which not only can achieve the reconstructed image of full search algorithm but also can greatly reduce both the codeword search ratio and chip area. in order to improve coding efficiency, a new algorithm called correlation - inheritance coding is proposed, which is embedded in conventional vq system to improve compression ratio by re - encoding the indexes

    首先，在普通矢量量化基礎上提出了等和值塊擴展最近鄰快速碼字搜索演算法（ ebnns ） ，該演算法在圖像畫質達到窮盡搜索演算法的前提下，大大降低了碼字搜索率和硬體實現面積；為了提高編碼效率，在相關性編碼方面，提出了相關繼承編碼演算法，對普通矢量量化后的編碼索引進行無損重編碼。
  3. Based on the analysis, we bring up a new way of thinking, after considering the characteristics of the dds design in software radio system platform. we adopt the rom compression technique of dds special chip and other optimizing methods in the design. we still bring up a new modified method, of which the compression ratio is 139. 6 : 1

    在此理論分析基礎上，針對在軟體無線電平臺中的直接數字頻率合成設計特點，對dds專用晶元進行分析后提出新思路，將dds專用晶元中所使用的幅度表壓縮技術用於軟體無線電平臺中的dds設計，同時採用其它輔助方法進行了優化設計，並提出一種新的改進方法，將壓縮比提高到139 . 6 ： 1 ，很好的改進了軟體無線電平臺中直接數字頻率合成的雜散抑制性能。
