A replacement for this product is available:
Note: Model number E8873A has been discontinued; however, the TD-SCDMA Design Library feature/capability is now included in the W2363 Mature Wireless Libraries Element.
The information below is provided for reference only.
E8873A TDSCDMA Design Library provides behavioral models, and pre-configured Test and Verification setups which evaluate design performance parameters such as Error Vector Magnitude (EVM), Power versus Time, Complementary Cumulative Distribution Function (CCDF), and coded Bit Error Rate (BER), and more.
The E8873A TDSCDMA Design Library makes it possible to rapidly develop TDSCDMA designs in ADS. It also helps verify those designs against the TDSDMA specifications.
Pre-Built Algorithmic (Behavioral) Models for ADS
Pre-built ADS algorithmic models are supplied for coded uplink and downlink sources. Models for Convolutional coding, Turbo coding, interleaving, rate matching, multiplexing, and many others are provided.
Pre-Configured Test and Verification Projects
Pre-configured Test and Verification projects help with design verification throughout the design process. Designs can be tested, at any point in the design cycle, against many of the transmitter and receiver specifications in the TDSCDMA technical specifications.
The TDSCDMA Design Library contains baseband functionality including framing, encoding, interleaving, and apreading to help model the physical channel of a TDSDMA system.
These library elements support rapid, parallel design cycles by making an RF system and circuit design baseline available well before the baseband designs are complete. When the designs are ready, simply substitute the actual baseband designs for the library elements.
Connectivity to Test Equipment
Connectivity between the Advanced Design System and test equipment, " Connected Solutions", helps bridge the gap between design and test, combining with the TDSCDMA Design Library to create a seamless design flow.
TDSCDMA Algorithmic (Behavioral Models)
The E8873A TDSCDMA Design Library contains the following pre-built algorithmic models. These models are also know as behavioral models.
The models can be used as a starting-point for designs, or to provide the baseband functionality needed to begin evaluation of RF, system, and baseband designs.
- Uplink and Downlink configurable sources
- Convolutional coding
- Turbo coding
- Rate matching and multiplexing
- 1/2/4/8/16 Orthogonal Variable Spreading Factors (OVSF)
- Complex scrambling
- Multiple code channels
- Multiplexing for data, TFCI bits, SS bits, and TPC bits for DPCH
- Rake receiver
- Joint Detection receiver
Pre-Defined TDSCDMA System Measurements
The TDSCDMA Design Library contains a number of key pre-defined system measurements. Among them are the following:
- Coded Bit Error Rate (BER)
- Block Error Rate (BLER)
- Error Vector Magnitude (EVM)
- Complementary Cumulative Distribution Function (CCDF)
- Power Versus Time
- Multi-Carrier Test
