5g_channel

5G NR 信道模型：目前仅实现了路径损耗 (7.4.1) 和 LOS 概率 (7.4.2)

Reference

3GPP TR 38.901 V16：研究 0.5 至 100 GHz 频率的信道模型，第 7 章 0.5-100 的信道模型GHz

Usage

选项 1：导入所有函数

const g5_channel = require('5g-channel');

g5_channel.pathloss.pathloss_rma_los(2, 400); // 2 GHz，400 米距离

g5_channel.prLos.pr_los_rma(400);

选项 2：选择性导入

const { pathloss_rma_los } = require('5g-channel/pathloss') ;

pathloss_rma_los(2, 400)

Includes: pathloss and line-of-sight probability for the following scenarios

## Rural Macro

• LOS概率：pr_los_rma(d_2d_out)

• Pathloss：

  • LOS: pathloss_rma_los(fc, d_2D, h_BS, h_UT, W, h)
  • NLOS: pathloss_rma_nlos(fc, d_2D, h_BS, h_UT, W, h)
  • Average: pathloss_rma(fc, d_2D, h_BS, h_UT, W, h)

  Urban Macro

• LOS概率：pr_los_uma(d_2d_out, h_UT)

• > 路径损失：

  • LOS: pathloss_uma_los(fc, d_2D, h_BS, h_UT, h_E)
  • NLOS: pathloss_uma_nlos(fc, d_2D, h_BS, h_UT, h_E, option)
  • Average: pathloss_uma(fc, d_2D, h_BS, h_UT, h_E, option)

  Urban Micro-streen canyon

  Indoor-office (InH)

• LOS概率：

  • mixed office: pr_los_inh_mixed(d_2d_in)
  • open office: LOS probability: pr_los_inh_open(d_2d_in)
  • both types: LOS probability: pr_los_inh(type, d_2d_in)

• Pathloss：

  • LOS: pathloss_inh_los(fc, d_3D)
  • NLOS: pathloss_inh_nlos(fc, d_3D, option)
  • Average: pathloss_inh(fc, d_3D, d_2D, type, option)

  Infoor Factory (InF)

• LOS概率：pr_los_inf(type, d_2d, h_BS, h_UT, h_c, r)

• 路径损失：

  • LOS: pathloss_inf_los(fc, d_3D)
  • NLOS: pathloss_inf_nlos(fc, d_3D, type)
  • Average: pathloss_inf(fc, d_3D, h_BS, h_UT, h_c, r, type)

  Different types of InF

  • InF-SL (sparse clutter, low BS)
  • InF-DL (dense clutter, low BS)
  • InF-SH (sparse clutter, high BS)
  • InF-DH (dense clutter, high BS)
  • InF-HH (high Tx, high Rx)
