Simulation result shows that the scheme is valid to suppress directional strong interference for stbc mimo system although with some performance loss compared with the ideal case of non - interference 仿真結(jié)果表明該方案雖然相對于理想無干擾的系統(tǒng)來說有一定的性能損失,但是能有效抑制空時分組碼mimo系統(tǒng)中的強定向干擾。
This is not only conceptually elegant , but also allows each different implementation of dom to expose its own classes via the standard interfaces , without the performance loss of going through intermediate wrapper classes 這不僅是概念上完美,而且還允許每個dom的不同實現(xiàn)通過標(biāo)準(zhǔn)接口使其自身的類可見,并且沒有通過中間包裝類所導(dǎo)致的性能損失。
In the serial computation domain , people acknowledged von neumann machine model as computation model . so serial programs can be transported to other serial computers without much alteration and potential performance loss 在串行計算領(lǐng)域,大家都公認了以馮諾依曼模型為計算模型,因而串行程序基本上無須多大改變就可移植到其它的串行計算機上,并且無潛在的性能損失。
3 . by theoretical analysis and simulation , quantization decoding of ldpc codes is studied . an efficient quantization - decoding scheme is proposed which can greatly reduce the decoding complexity with a little performance loss 采用理論分析和仿真相結(jié)合的方法研究了ldpc碼的量化譯碼,提出了一種高效的量化譯碼實現(xiàn)方案,該方案能夠大大降低譯碼復(fù)雜度,同時譯碼性能非常接近連續(xù)譯碼。
The mixing degree model was established to study the mixing progress of primary and secondary flow . the loss elements of all zones were deeply analyzed and thus the quantitative loss models based on total pressure loss and entropy increase respectively were constructed . the results show that the performance loss magnitude and distribution in ejecting mode of rbcc can be better described by the quantitative loss model expressed by entropy increase 提出用摻混度模型來研究一次流與二次流的摻混程度,并深入分析了各流動區(qū)域的損失因素,建立了以總壓損失和熵增分析為基礎(chǔ)的損失量化分析模型,計算的結(jié)果表明,采用熵增模型描述的損失因子能量化反應(yīng)引射摻混損失的分布和大小。
