According to the gjb 2077 - 94 and the requirement of automatic radio of haige communication co . , a new way of bit synchronization is put forward . this article discusses the design of 8 - fsk modulating and demodulating , signal detection , and fec encoding , based on the technique of bit synchronization . ale module is optimized and mended in its application , because it is a module of automatic radio of the company 本文根据gjb2077 - 94短波自适应通信系统自动线路建立规程和海格通信公司短波自适应电台对ale模块的具体需求，采用了一种新的位同步方法：能量跟踪法，并在此基础上提出了8fsk调制解调，信号检测，前向纠错编码的具体实现方法。
And now there are 400 staff and worker in the factory , which has the ability of annual production 4 million sets per year for tapered roller bearings , cylindrical roller bearings and ball bearings , fixed assets rmb 103 million yuan , output value rmb70 million yuan . the factory has built medium - small sized tapered roller bearing production line which will be put into production in recent dates which production is 2 million sets in a year 该厂为机电部生产轴承的重点企业，现有固定资产10300万元，职工4000余人，是国家大型企业，工厂占地面积262000平方米，厂房面积65815平方米，年可产0 2 7三大类型的滚子轴承400万套，中小型园锥滚子轴承自动线项目，于近期投产。
