Method and Apparatus for Sparse Polynomial Equalization of RF Receiver Chains

Radio-frequency (RF) receivers are critical components in wireless communications. With the rising demand for such communications, it becomes essential to increase the efficiency of these receivers. Traditionally, RF receivers face problems like signal distortion that impacts the overall communication quality, necessitates innovation in RF receivers. Most existing approaches focus on completely digitalizing the receiver, which can increase the linearity performance and consume a lot of power. This power consumption becomes a significant hindrance in creating efficient, effective, and sustainable RF receiver designs.

Technology Description

The technology is a radio-frequency (RF) receiver that includes an analog receiver chain coupled with digital circuitry to mitigate nonlinear distortion components in the output signal. The digital circuitry utilizes a digital equalizer that operates using a sparse set of Volterra series coefficients. This design feature eliminates unnecessary operations in the digital equalizer, making it more efficient. The uniqueness of the technology lies in its fusion of analog and digital elements, specifically the digital equalizer equipped with a sparse set of Volterra series coefficients. It successfully strikes a balance between optimal linearity performance and power conservation. This blend of efficient operational design with digital circuitry makes the technology stand out in the receiver technology space.
