Method for improving low-intermediate frequency receiver performance
A recently granted patent (Publication Number: US11990927B2) discloses a method for enhancing the performance of a low-intermediate frequency receiver. The method involves selecting a local oscillator signal from a preset frequency set to mix with an input signal, generating a low-intermediate frequency signal. This signal comprises both useful and interference components. By analyzing the energy ratio between the interference and useful signals, the method dynamically adjusts the local oscillator signal to optimize performance. Additionally, the method includes detecting and addressing errors in a synchronous code within the low-intermediate frequency signal, further enhancing the receiver's efficiency.
Furthermore, the patent extends to a non-transitory computer-readable storage medium and a low-intermediate frequency receiver implementing the disclosed method. The computer program stored in the medium, when executed by a processor, facilitates the performance-enhancing method for the receiver. The receiver, equipped with a memory and processor, leverages the method to manage the energy ratio between interference and useful signals, adapt local oscillator signals, and address synchronous code errors. This innovation aims to improve the overall functionality and effectiveness of low-intermediate frequency receivers, particularly in scenarios where adjacent channel interference and squelch conditions may impact signal quality. By dynamically adjusting parameters based on energy ratios and error detection, the method offers a sophisticated solution for optimizing receiver performance in various operational environments.
