Physical downlink shared channel
Syntax
描述
例子
Generate PDSCH symbols for Test Model E-TM1.1 10MHz
Generate the configuration structure for Test Model E-TM1.1 10 MHz, as specified in TS36.141
Initialize the test model usingltetestmodel
。生成与PDSCH索引相关的信息并使用info.gd
输出以确定所需的运输块。执行Letterlsch
要创建代码字,然后生成PDSCH符号。
tm = lteTestModel('1.1','10MHz'); tm.PDSCH.RNTI = 0; tm.PDSCH.RV = 0; prbset = (0:tm.NDLRB-1)'; [ind,info] = ltePDSCHIndices(tm,tm.PDSCH,prbset); trBlk = randi([0,1],info.Gd,1); cw = lteDLSCH(tm,tm.PDSCH,info.G,trBlk); pdschSym = ltePDSCH(tm,tm.PDSCH,cw);
