Based on orthogonal cyclic codes, a dual M-ary orthogonal SS ( Spread Spectrum) system scheme is presented to transmit high rate data. It can reduce the difficulty of selecting PN codes and increase user numbers in the system. 以正交循环码为基础,提出了一种适合于高速业务传输的双多进制正交扩频系统方案,降低了系统选码的难度,提高了用户容量。
First, we used Markov model to analyze the dual fault-tolerance system and pointed out the important influences of failure detection mechanism with high coverage and success rate to the availability of system. 通过马尔科夫模型对双模系统进行分析,指出了高覆盖率和高成功率的故障检测机制对系统可用性的重要影响。
