LTE Throughput Analyzer
Generate throughput curves for physical downlink shared channel (PDSCH) conformance test analysis
描述
这LTE Throughput Analyzer应用执行PDSCH解调性能测试。TS 36.101[1],附件A.3指定UE性能测试的RMC。
这app also performs analysis and testing for custom user-defined measurement channels settings. For an example, seeLTE Throughput Analyzer User-Defined Testing。当传输方案时,该方法也可以用于模拟传输模式7-10(TxScheme
) is'Port5'
,'Port7-8'
,'port8'
, or'port7-14'
PDSCH解调需要基于DM-RS的通道估计。在这种情况下,预编码矩阵W
根据TS 36.101随机定义每个子框架[1], Table 8.3.1-1 for FDD and Table 8.3.2-1 for TDD.

例子
执行4 by-2传输多样性一致性测试
Use theLTE Throughput Analyzerapp to run a conformance test for a single codeword RMC R.12-9RB for the transmit diversity transmission scheme with EPA-5 fading.
Open theLTE Throughput Analyzer应用程序。
Adjust default runtime parameter settings:
Set参考通道to
R.12-9RB
。ForSNR (dB), enter
[-3.0 -1.0 1.0 3.0]
。For仿真长度(帧), enter
20
。
Select开始模拟。该应用程序提供了预计剩余时间。模拟完成后,对话框显示性能曲线。
20帧运行的仿真结果显示在MATLAB命令窗口中。

LTE Throughput Analyzer User-Defined Testing
Open the LTE throughput analyzer app and run a user-defined measurement channel. Define a custom measurement channel. You can select any RMC and change any settings, though care must be taken not to define an invalid configuration.
对于此示例,以R.3 RMC开始,然后将资源块数量从50调整到30。
CMC= lteRMCDL('R.3');cmc.ndlrb = 30
CMC=带有字段的结构:RC: 'R.3' NDLRB: 30 CellRefP: 1 NCellID: 0 CyclicPrefix: 'Normal' CFI: 2 PCFICHPower: 0 Ng: 'Sixth' PHICHDuration: 'Normal' HISet: [112x3 double] PHICHPower: 0 NFrame: 0 NSubframe: 0 TotSubframes: 10 Windowing: 0 DuplexMode: 'FDD' PDSCH: [1x1 struct] OCNGPDCCHEnable: 'Off' OCNGPDCCHPower: 0 OCNGPDSCHEnable: 'Off' OCNGPDSCHPower: 0 OCNGPDSCH: [1x1 struct]
Open the LTE throughput analyzer app.
