摘要

无线电传输中断导致了一种影响,这种影响可能会导致接收器信号质量的下降。抑制可变影响的解决方案之一是接受者一侧的空间增量的使用。这项研究使用的是一种广泛的空间分散技术,它结合了各向结合、均等增益联合和最大比例联合,以获得更有效和更有效的混合性能。模拟使用了一些运河的b妓女调制,如Rayleigh, Rician, Nakagami-m, Weibull和Suzuki。MATLAB的模拟结果表明,一般来说,运河的入学率提高了,在那里,铃木运河的入学率最低,而在Weibull运河的入学率最高。关键词:fading,空间多样性,rayleigh, rician, weibull, nakagami, suzuki。缺席会影响接收器高强度信号的损害。其中一种解决方案是利用现有的空间多样性。在这项研究中,一种动态空间多元化联合技术已被使用,该公司正在使用,以获得更有效和最有效的组合表现。模拟是在加拿大的several types、namely Rayleigh、Rician、Nakagamim、Weibull和Suzuki上使用bcock模块。MATLAB模拟结果显示,在普遍的加拿大,铃木海峡发生了2起dB事件,而highest则是Weibull运河上的4起dB事件。事实,空间多样性,雷,里西亚,威布尔,中川,铃木。

Dynamic Spatial Diversity Combiner pada Kanal Fading
ABSTRAKKanal transmisi radio berkontribusi pada terjadinya efek fading yang dapat berpengaruh pada terjadinya penurunan kualitas sinyal pada penerima. Salah satu solusi yang digunakan untuk menekan efek fading adalah penggunaan Spatial Diversity di sisi penerima. Pada penelitian ini digunakan suatu teknik Dynamic Spatial Diversity Combining yang memadukan Selection Combining, Equal Gain Combining, dan Maximal Ratio Combining untuk mendapatkan kinerja combiner yang lebih efektif dan efisien. Simulasi dilakukan dengan menggunakan modulasi BPSK pada beberapa jenis kanal yaitu Rayleigh, Rician, Nakagami-m, Weibull, dan Suzuki. Hasil simulasi MATLAB menunjukkan bahwa secara umum kanal yang mendapatkan perbaikan kinerja penerimaan, dimana nilai terendah sebesar 2 dB terjadi pada kanal Suzuki dan tertinggi sebesar 4 dB pada kanal Weibull.Kata kunci: fading, spatial diversity, rayleigh, rician, weibull, nakagami, suzuki. ABSTRACTRadio transmission channels contribute to the occurrence of fading effects that can affect the decrease in signal quality at the receiver.
