LTE_Toolbox_datasheet_v3.0
Overview
3G Evolution Lab – LTE Library Toolbox v3.0 is a comprehensive physical layer
simulation Toolbox for Release 8 of the 3GPP Evolved Universal Terrestrial Radio Access (E-
UTRA) standard. The library will accelerate your algorithm and PHY development, support
golden reference verification and enable test & measurement waveform generation.
The Toolbox features functions to perform channel coding/decoding and
modulation/demodulation operations implementing the full physical layer transmit/receive
processing chain (FDD and TDD), from transport channels and control information to OFDM
and SC-FDMA modulated waveforms. Receive models are offered to recover the transmitted
signals. Channel coding for transport channels and control information is available for
uplink and downlink. Test Models and Reference Measurement Channel (RMCs) waveform
generators are available to easily create reference waveforms.
The development roadmap includes tracking compliance from Release 8 into Release 9 and
LTE-Advanced.
The following transport and physical channels and signals are supported:
Downlink Uplink Transport Channels & Control Information Transport Channels & Control Information
DL-SCH HI UL-SCH UCI
BCH CFI PRACH
DCI
Physical Channels and Signals Physical Channels and Signals
PDSCH PDCCH PUSCH SRS
