Design Notes

LTE Uplink User Equipment RX Test Bench

This example demonstrates:

LTE FDD Uplink TX, compliant with 3GPP specifications.

Specification document: TS 36.104, TS 36.211, TS 36.212

Configurable options include:

- CarrierFreq_MHz : carrier frequency of the signal in MHz

- TxOutLvlStart_dBm, TxOutLvlSpan_dBm, TxOutLvlStep_dBm: define swept power of transmitted signal

- FrameType: frame type and cycling preffix:

- 0: Frame structure type 1 / Normal CP: FDD

- 1: Frame structure type 2 / Normal CP: TDD

- 2: Frame structure type 1 / Extended CP: FDD

- 3: Frame structure type 2 / Extended CP: TDD

- N_RB_UL: number or resource blocks used for transmission; determines the channel bandwith as defined in the specifications (See Global Definitions for relationship between N_RB_UL and channel BW).

- ModType: modulation type (QPSK, 16QAM, 64QAM)

- RB_PATTERN_INDX: indexes of the resource blocks assigned to the uplink transmission

- BlkLen: payload size in bits as defined in TS 36.104, Annex A.

The test bench can be used to monitor:

- The TX signal spectrum at various points

- IQ constellation of the transmitted and demodulated signals

- Bit error rate (BER) and block error rate (BLER)

- CRC error for each block
