EQUALIZATION DOMAIN SELECTION AT A WIRELESS DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17894025 titled 'EQUALIZATION DOMAIN SELECTION AT A WIRELESS DEVICE
Simplified Explanation
- The patent application describes systems, methods, and apparatus for equalization domain selection at a wireless device. - A wireless device can choose between time domain equalization and frequency domain equalization for receiving RF signals based on detected channel conditions. - If the channel is relatively dispersive, frequency domain equalization may be selected. If the channel is relatively flat, time domain equalization may be chosen. - Time domain equalization may involve changing the sampling rate to match the symbol rate, such as through resampling using a Farrow resampler. - The wireless device may select an equalization scheme with the lowest power consumption for the detected channel conditions.
Potential Applications
- Wireless communication systems - Mobile devices - Internet of Things (IoT) devices
Problems Solved
- Efficient equalization selection based on channel conditions - Power consumption optimization - Improved signal reception in varying channel conditions
Benefits
- Enhanced signal quality - Increased power efficiency - Adaptability to changing channel conditions
Original Abstract Submitted
This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for equalization domain selection at a wireless device. A wireless device may be configured to support a selection between time domain equalization and frequency domain equalization for receiving RF signals, which may be performed in accordance with detected channel conditions. For example, if a wireless device detects conditions associated with a relatively dispersive channel, the wireless device may select a frequency domain equalization and, if the wireless device detects conditions associated with a relatively flat channel, the wireless device may select a time domain equalization. In some implementations, performing a time domain equalization may include changing a sampling rate into a symbol rate, such as performing a resampling using a Farrow resampler. Such techniques may include a wireless device selecting an equalization scheme associated with a relatively lowest power consumption for detected channel conditions.
