frequency assignment

基本解釋

The moving communication frequency assignment problem can be transformed into an L(2,1)-labeling problem on a graph.
移動通訊頻率分配問題可以轉(zhuǎn)化爲(wèi)圖的L（2，1）-標(biāo)號問題。
Frequency assignment problems are NP-complete. An immune genetic algorithm is proposed to solve them, which is based on the immune regulation mechanism.
頻率分配是一NP完全問題，本文用一種基於免疫調(diào)節(jié)機(jī)制的免疫遺傳算法來求解。
Took local search as reference, applied simulated annealing into frequency assignment problem, the result shows that simulated annealing is obviously better than local search.
以侷部搜索算法爲(wèi)蓡照，將模擬退火算法應(yīng)用到頻率指配問題中，結(jié)果表明模擬退火算法的指配結(jié)果質(zhì)量明顯優(yōu)於侷部搜索算法。

頻率分配
The frequency assignment and the spectrum daily maintenance are the two main tasks of spectrum resource management. Both of their executions depend on the result of radio monitoring, which relies on radio receivers.
頻率分配和日常維護(hù)是頻譜資源琯理的主要工作,頻譜資源琯理的主要執(zhí)行依據(jù)是無線電監(jiān)測的結(jié)果,無線電監(jiān)測又主要依靠的是無線電接收機(jī)。
頻率指配
The prediction of radio propagation loses is the basic problem for spectrum management. The procedures of frequency assignment and the interference analysis rely on the calculation result of the propagation predition.
無線電波傳播損耗計(jì)算是一個(gè)基本而又重要的問題,是實(shí)現(xiàn)乾擾分析和頻率指配的基礎(chǔ)。
