W1916 3G Baseband Verification Library

The W1916 3G Baseband Verification Library is an optional simulation reference library for Keysight Technologies SystemVue. It is intended for design and system-level verification of the physical layer (PHY) of 2G and 3G wire­less commercial mobility standards. It consists of several sub-libraries with simulation blocks for baseband signal encoding (TX), decoding (RX), channel, and measurement, along with pre-configured test benches for many PHY specifications in the standards, as well as other common measurements.

-Simulation-based verification of legacy 2G/3G standards performance for 4G/LTE equipment

-“Multi-Standard Radio” (MSR) validation related to the Third Generation Partnership Project (3GPP) Rel.9 TS36-104 and TS36-147

-Custom PHY modifications for military, medical and com­mercial wireless

-Reference test vectors for baseband DSP/FPGA and RF component validation (both simulation and test equipment)

-Reference signal generation for the SystemVue W1716 Digital Pre-Distortion (DPD) Builder

GSM/EDGE

The GSM/EDGE portion of the W1916 3G Baseband Library was developed according to 3GPP GSM Release 10 (updated March 2012). The library provides a total of 61 models and subnets, including several top-level GSM/EDGE sources and receivers.

CDMA/CDMA2000^®

The CDMA/CDMA2000 portion of the W1916 3G Baseband Verification Library helps communication and RF system designers perform system-level tradeoffs, requirement partitioning and performance verification based on the TIA IS-95, IS-96A and IS-2000 standards.

The library allows the simulation of key transmitter and receiver measurements such as Error Vector Magnitude (EVM), Adjacent Channel Power Ratio (ACPR), Bit Error Rate (BER), and Frame Error Rate (FER). The library also helps component designers validate the performance of their subsystem against CDMA/CDMA2000 specifications.

The CDMA/CDMA2000 portion of the W1916 3G Baseband Verification Library includes advanced features such as hybrid phase-shift keying (HPSK) spreading (reverse link), pilot-aided coherent demodulation (reverse link); channel coding including turbo codes, mapping and de-mapping schemes for rate matching; and orthogonal transmit diversity (OTD).

W-CDMA

The 3GPP FDD (or W-CDMA) portion of the W1916 3G Baseband Verification Library enables design and valida­tion against the specifications from the 3GPP Frequency Division Duplexing (FDD) Wideband Code Division Multiple Access (W-CDMA) standard. The library provides baseband functionality such as framing, encoding, interleaving, and spreading to model the physical channel in the 3GPP FDD W-CDMA system.

HSPA

The HSPA portion of the W1916 3G Baseband Verification Library is designed for High Speed Packet Access plus (HSPA+), an enhancement to the 3GPP downlink/uplink defined in release 7 of the 3GPP specification. This design library focuses on the physical layer aspects of High-Speed Downlink Packet Access (HSDPA) systems. It is intended to serve as a baseline for designers to get an idea of what would be the nominal or ideal system performance. Evaluations can be made regarding degraded system performance due to system impairments that may include non-ideal component performance.

The transport channels and physical channels defined in previous versions of the 3GPP specification are also supported by the HSDPA design library. They are treated as accessory channels because the HSDPA design library focuses on the modeling and test of channels defined in Release 5, say HSDPA. The test for the scenario with only 3GPP FDD and without HSDPA can be implemented by the 3GPP design library.
