Dalam makalah ini, kapasiti erlang pautan hadapan dan kebarangkalian terputus untuk sistem selular hierarki berdasarkan 2 lapisan makrosel/mikrosel diperoleh secara analitikal dengan mengambil kira kesan kawalan kuasa yang tidak sempurna dan penyerahan lembut. Analisis kebarangkalian gangguan dijalankan menggunakan dua kaedah: penghampiran lognormal dan sempadan atas Chernoff. Kami menganggap bahawa pengguna perkhidmatan data suara dan berbilang kadar diedarkan secara seragam dalam setiap sel dan spektrum yang sama digunakan dalam kedua-dua lapisan. Di samping itu, kami mengambil kira nisbah kuasa penghantaran stesen pangkalan antara peringkat dan kedudukan relatif mikrosel yang mempunyai pengedaran pulau dalam makrosel. Gangguan pautan ke hadapan dinilai dengan menggunakan simulasi Monte-Carlo yang diperkenalkan dalam [2]. Dalam kertas kerja ini, kami membandingkan kapasiti erlang pautan hadapan sistem 1x kepada sistem 3x dan menunjukkan bahawa sistem 3x boleh meningkatkan kapasiti pengguna sebanyak 3.4 kali ganda dalam kes makrosel dan mikrosel, masing-masing, berbanding sistem 1x.

Abstract: In this paper, the forward link erlang capacity and outage probability for hierarchical cellular system based on 2 layer macrocell/microcell are derived analytically by considering the impact of imperfect power control and soft hand-off. The analysis on the outage probability is carried out using two methods: lognormal approximation and Chernoff upper bound. We assume that voice and multi-rate data service users are distributed uniformly in each cell and the same spectrum is applied in both layers. In addition, we take into account the base station transmission power ratio between tiers and the relative position of microcell having island distribution in macrocell. The forward link interference is evaluated by using Monte-Carlo simulation introduced in [2]. In this paper, we compare the forward link erlang capacity of 1x system to 3x system and show that 3x system can increase the user capacity by 3.4 times in case of macrocell and microcell, respectively, compared to 1x system.
