Request your free trial license today: TD-SCDMA technology overview Time division-synchronous code division multiple access (TD-SCDMA) combines FDMA and CDMA technologies. Unlike W-CDMA and cdma2000 technologies, this TDD standard transmits and receives on the same frequency, which greatly increases spectrum efficiency. Because TD-SCDMA effectively handles symmetrical and asymmetrical traffic, it is ideal for data-intensive applications, such as mobile internet access and multimedia applications. TD-SCDMA was proposed by the China Wireless Telecommunication Standards group (CWTS) and approved as a 3G technology by ITU in The TD-SCDMA standard is fully supported by 3GPP and the China Communication Standards Association (CCSA). The 3GPP TD-SCDMA standard is also known as the low chip rate (LCR) option of TDD, which is included in the 3GPP Universal Terrestrial Radio Access (UTRA) as the UTRA-TDD option. 3

Analysis and Troubleshooting Gain insight into your signal with 20:20 visibility The 89600B VSA software profi les the signal s power over time with up to 20 traces with 20 markers each, allowing you

An error summary table provides detailed pilot phase coding information and individual timeslot error data, with chip timing, total power, midamble power and data fi eld power error information.

4 Analysis and Troubleshooting Gain insight into your signal with 20:20 visibility The 89600B VSA software profi les the signal s power over time with up to 20 traces with 20 markers each, allowing you to look at overall, composite, and layer performance, simultaneously. An error summary table provides detailed pilot phase coding information and individual timeslot error data, with chip timing, total power, midamble power and data fi eld power error information. Compare all these values at baseband, IF, and RF. View overall, composite, and layer data. The Overall Time trace, which provides an arrow to indicate the uplink/downlink status of each timeslot, shows timeslot 6 selected. IQ constellations for the layer and composite signals appear in Traces E and C. Insightful display formats help characterize signals. Here, a captured signal has been replayed using overlap processing to effectively slow it down. The cumulative history display format (Trace B), highlights signal performance over very long periods. 4

Review your signal s performance with CDE and CDP data Code domain error (CDE) and code domain power (CDP) results are available for the layer or the composite

The CDE of a particular code channel is a measure of the error power in a code channel relative to the total signal power.

Together they provide key insight into the performance of a TD-SCDMA system.

5 Review your signal s performance with CDE and CDP data Code domain error (CDE) and code domain power (CDP) results are available for the layer or the composite signal in either averaged or instantaneous value form. The CDE of a particular code channel is a measure of the error power in a code channel relative to the total signal power. CDP is an analysis of the distribution of signal power across the set of code channels normalized to the total signal power. Together they provide key insight into the performance of a TD-SCDMA system. CDE and CDP data is shown in a multi-color format that assigns a unique color to each active code layer, for easy visual identification. Markers on the composite trace help with the identification of code layers. Dynamic Help quickly links you to the explanation of a menu or trace. Here, it provides information on the Channel/Layer tab where you can select the desired despread channel and CDP code layer that you would like to display. 5

Get a clear view of composite signals Composite denotes trace data results for the composite signal, which includes all spread code lengths (symbol rate) and code channels.

6 Get a clear view of composite signals Composite denotes trace data results for the composite signal, which includes all spread code lengths (symbol rate) and code channels. These measurements, useful for evaluating the overall in-band performance of the signal, include: composite code domain power (CDP) and composite code domain error (CDE), as well as time domain measurements such as rho, EVM, EVM spectrum, and EVM time. Detailed error information on the composite signal performance of a single timeslot provides the next layer of powerful troubleshooting. Note that for error traces with time (chips) on the x-axis, the midamble location is denoted. 6

Open a window into your signal with channel analysis The 89600B lets you look at your signal one channel at a time.

Detailed channel error summary data provides both bit demodulation and detailed overall error measurements.

Use the Channel/Layer tab of the Demodulation Properties tab to select a despread channel.

7 Open a window into your signal with channel analysis The 89600B lets you look at your signal one channel at a time. Specify the code channel and spread code length to uniquely specify a channel, and you can look at its IQ trajectory and errors over time. Detailed channel error summary data provides both bit demodulation and detailed overall error measurements. The Channel Error Summary table provides detailed modulation quality statistics for a selected channel/ layer. Phase and Magnitude Error traces are available to examine error over time. Use the Channel/Layer tab of the Demodulation Properties tab to select a despread channel.
