一种用于数字地震仪的低功耗RS编码方法
|
摘要
针对RS(里德-所罗门)编码实现时所需功耗过高,导致其很难被应用到对功耗要求非常严格的环境中这一问题,文中在对影响编码实现功耗的各因素进行分析的基础上,提出一种适用于数字地震仪中的低功耗RS编码方法。该方法相比于传统的已提出的实现方法在计算复杂度、延迟及功耗等性能方面的优势均有明显提升。仿真结果表明,用此编码方法实现的RS(31,27)编码,可以在满足数字地震仪对低功耗的要求下,达到数字地震仪对传输可靠性的要求。
To solve the problem that the RS coding has too high pow er consumption to be used in low pow er consumption system,a method for low pow er RS coding in digital seismograph is presented,on the basis of analyzing each factor which has influence on the coding pow er in this paper. Compared with the traditional proposed one,the method has low computational complexity,smaller delay and low er pow er consumption. The simulation results show that the RS( 31,27) code realized by this coding method,can meet the requirements of digital seismic instrument on the transmission reliability in low pow er consumption condition.
