LTE FDD Uplink User Equipment TX 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:
� NFramesSweep: number of 10ms frames used in each sweep
� TxOutLvlStart_dBm, TxOutLvlSpan_dBm, TxOutLvlStep_dBm: Define swept power of transmitted signal
� Carrier Frequency (MHz)
� PayloadSize (bits): Block size defined in TS 36.104, Annex A.
� MinNumBlkErrsCollect: minimum number of block errors collected for each signal level. This parameter determines when to move to the next the signal level. Block errors are calculated based on the decoded CRC.
� MaxNumBlockRun: maximum number of blocks generated for each signal level. If after MaxNumBlockRun blocks the number of collected errors is smaller than MinNumBlkErrsCollect, the simulation for that signal level is terminated.
� FrameType: frame type and cycling prefix:
- 0: Frame structure type 1: FDD
- 1: Frame structure type 2: 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).
� RB_Indxs: indexes of the resource blocks assigned to the uplink transmission
� ModType: modulation type (QPSK, 16QAM, 64QAM)
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
