lteCellRS

Cell-specific reference signal

阿胶pse all in page

Syntax

sym = ltecellrs（enb）
sym = lteCellRS(enb,ports)

Description

sym= lteCellRS(enb)returns cell-specific reference signal symbols for cell-wide settings in theenb结构体。symis a complex-valued column vector containing cell-specific reference signal symbols. Unlike other physical channels and signals, the symbols for multiple antennas are concatenated into a single column rather than returned in a matrix with a column for each antenna. The reason for this behavior is that the number of symbols varies across the antenna ports.

example

sym= lteCellRS(enb,ports)returns cell-specific reference signal symbols for antenna ports specified in the vector,ports(0, 1, 2, 3),和它是设置结构,enb。在这种情况下，CellRefPis ignored if present inenb和portsis used instead.

This example shows different numbers of cell-specific reference signal symbols transmitted at antenna port 0 and 2.

Initialize cell wide parameter structure,enb, to RMC R.6

enb = lteRMCDL('R.6');

Observe the number of cell-specific reference symbols on port 0

cellRefPort0 = length(lteCellRS(enb,0))
cellRefPort0 = 200

Observe the number of cell-specific reference symbols on port 2

cellRefPort2 = length(lteCellRS(enb,2))
cellRefPort2 = 100
