LTE PHY Lab is designed to serve customers at all stages of the LTE software, hardware and IPR development – from research, prototyping and implementation, up to system benchmarking, verification and testing.
LTE PHY Lab is a complete implementation of E-UTRA physical layer according to 3GPP Release 8, with substantial elements of Release 9 and 10. It runs under Matlab and can be used as a link-level simulation tool or a reference of the PHY library.

LTE PHY Lab is implemented as a library of modular functions with well-defined interfaces, which allows the user to experiment with the whole system, or any part of it – including providing his own implementation for selected components. There are plenty of predefined use cases and examples with well-documented functions. LTE PHY Lab is additionally designed to work with 5G waveforms – the first 5G waveform implemented in LTE PHY Lab is Universal Filtered Multi-Carrier (UMFC).
LTE PHY Lab models a bit-by-bit and sample-by-sample baseband processing for UE and eNB physical (PHY) layer in both downlink and uplink. It implements all 3GPP-compliant functionalities for Transport Channels, Control Info, Physical Channels and Physical Signal processing (including channel coding, MIMO precoding and OFDM / SC-FDMA modulation) and extends it by possible 5G waveforms. LTE PHY Lab provides algorithms for signal reception and recovery, including time and frequency synchronization, channel estimation and correction, MIB / DCI / SIB1 decoding. The tool supports cooperation with popular SDR hardware (e.g., USRP), in order to generate or receive the LTE waveform using VHF / UHF/ SHF frequency ranges, as well as writing and reading of the complex samples to / from a file. The key operations for eNB transmitter and receiver are presented in Figures 1 and 2, respectively, whereas Figure 3 depicts the combined processing chain for end-to-end downlink transmission. The main scenarios for simulation and experimentation using LTE PHY Lab are presented in Figure 4.
