Design Notes

NR FDD Uplink RX Test Bench

This example demonstrates an NR FDD Uplink receiver test bench, compliant with the 3GPP 38 series specifications. The test bench allows user to configure the NR uplink signal source and channel characteristics. The receiver is configured automatically to match the settings used in the transmitter.

Some of the signal parameters that the user can change include:

- Signal level, SIGPWR_dBm, which is swept by the BER_EXT.BER_PUSCH block

- Number of resource blocks, N_RB_UL

- Carrier Frequency (MHz)

- Subcarrier spacing as allowed by NR specification

- Modulation and coding scheme, MCS, and the corresponding table, MTBST, as specified in the NR specifications

- Oversampling rate used in the simulation, OVRSMP

- PUCCH format according to Section 6.3.2 TS 38.211.

The test bench can be used to monitor various measurements. The following measurements are predefined:

- The signal spectra at various points

- IQ constellation of the transmitted and demodulated signals

- Bit error rate (BER)

- Throughput
