A wireless network emulation system undersamples log files when the conditions represented in the log files would require a faster refresh rate than the channel emulator can provide. A representative sample may be selected based on number of channel taps, delay spread, maximum value, or being first, last or otherwise identifiable within a group. The RF information from the selected sample is utilized as being representative of a group of related samples for a given time period corresponding to the refresh rate of the channel emulator.

System level emulation of TD-SCDMA wireless networks

Missing or unwanted parameter data indicative of wireless network conditions in a log file or playback file is replaced with substitute parameter data. The substitute parameter data can be calculated based on other data in the log file or playback file, selected from pre-defined data in storage, and provided by a user. The substitute parameter data may also be customized by the user via an interface.

Modifying log files and playback files used for wireless network emulation

One or more events recorded in one or more log files are recognized and processed by performing one or more operations including segmentation, modification, extraction, addition, and subtraction. The processed events are used to generate a playback file which is used by a channel emulator to perform testing.
