Signal analysis device for ofdm-modulated communication testing
The granted patent US12034492B2 describes a signal analysis device designed to process signals modulated using the Orthogonal Frequency Division Multiple Access (OFDM) method. The device includes a receiver for capturing the signal, a processor connected to a memory for executing computer-executable instructions, and a display screen for visualizing analysis results. The processor is tasked with calculating signal data, analyzing it for predetermined items across subframe slots in the time domain, and generating analysis results that indicate decoding success or failure. The device can decode signals in units of code blocks and display results for each code block, including additional analysis items such as constellations and frequency spectra.
Further features of the device include the ability to set frequency intervals for subcarriers in line with communication standards like 5G NR, with specific values ranging from 15 KHz to 120 KHz. Additionally, the device can output a trigger signal at predetermined timings to facilitate the extraction and analysis of IQ data from the signal. The display screen is configured to show analysis results side by side for each subframe slot, enhancing the user's ability to monitor signal performance and identify decoding errors effectively. Overall, the patent outlines a comprehensive approach to signal analysis that integrates advanced processing capabilities with user-friendly visualization tools.
