Multiple Access (LTE-Advanced Uplink)

Default: SCFDMA

Range: SCFDMA, SCMA

Multiple Access selects the multiple access technique to be used in the LTE Long Term Evolution-Advanced demod configuration. For LTE-Advanced Uplink, the choices are:

SCFDMA - The default multiple access value for LTE Uplink is SCFDMA.
SCMA - SCMA (Sparse Code Multiple Access) configures the LTE demodulator for SCMA, which is a new multiple access scheme introduced in 5G. In SCMA transmission, the data from multiple users or the data from multiple streams of a single user can be overlapped in the same time-frequency resource grids, with sparse code encoded. Currently this measurement is only available for the Uplink PUSCH Physical Uplink Shared Channel Sync Type.

Selecting SCMA enables the SCMA parameters under the 5G Candidate tab. Selecting SCMA also adds PUSCH_SCMA EVM Error vector magnitude (EVM): A quality metric in digital communication systems. See the EVM metric in the Error Summary Table topic in each demodulator for more information on how EVM is calculated for that modulation format. and Power results to the Frame Summary trace.
