有限字长运算 meaning in Chinese

finite word-length arithmetic

The matlab language and c language were applied to simulate the fixed - point dsp arithmetic of equalizer algorithm . the simulation result indicated the diveragence phenomenon would happen to adfe ( adaptive decision feedback equalizer ) based on rls algorithm under the fixed - point finite - precision arithmetic
采用matlab和c语言模拟均衡器定点dsp算法的实现，仿真结果表明rls算法的自适应判决反馈均衡器( adfe )在定点有限字长运算的情况下存在着发散现象。
