【摘要】：將方法無(wú)線電和應(yīng)用數(shù)學(xué)的原理引入多用戶差分跳頻網(wǎng)絡(luò),提出基于拉丁方的認(rèn)知差分跳頻自適應(yīng)頻率集方法.該方法在認(rèn)知后得到可用頻譜信息的基礎(chǔ)上,將跳頻頻率集劃分為頻率子集,按照動(dòng)態(tài)生成的拉丁方將頻率子集動(dòng)態(tài)分配給網(wǎng)內(nèi)用戶,使同一時(shí)隙內(nèi)用戶的頻率子集正交,從而抑制多用戶網(wǎng)絡(luò)的多址干擾,提高抗部分頻帶干擾以及多音干擾性能.仿真結(jié)果顯示該方法較傳統(tǒng)多用戶差分跳頻網(wǎng)絡(luò)可以顯著提高多址性能與抗干擾性能.
[Abstract]:The principle of method radio and applied mathematics is introduced into multi-user differential frequency hopping network, and a Latin square based cognitive differential frequency hopping adaptive frequency set method is proposed. Frequency hopping frequency sets are divided into frequency subsets, frequency subsets are dynamically allocated to users in the network according to dynamically generated Latin square, so that the frequency subsets of users in the same time slot are orthogonal, so as to suppress the multiple access interference of multi-user networks. The simulation results show that the proposed method can significantly improve the performance of multiple access and anti-jamming compared with the traditional multi-user differential frequency hopping network.
