Title: Olli Tapio: Innovator in Signal Processing
Introduction
Olli Tapio is a notable inventor based in Jääli, Finland. He has made significant contributions to the field of signal processing, holding a total of 3 patents. His work primarily focuses on methods and arrangements that enhance the performance of signal predistortion and RF amplifiers.
Latest Patents
Olli Tapio's latest patents include a method and arrangement for forming an address used in signal predistortion. This innovative arrangement is designed to create a corrector table address that compensates for signal distortions. The system utilizes corrector coefficients stored in a table, which are retrieved based on the calculated address. Additionally, the arrangement features calculation means that determine a result corresponding to the squaring of a received signal, along with summing means that aggregate these results to form a base address. Error correction means are also included to refine the calculated base address using an address correction value.
Another significant patent involves a linearization method for RF amplifiers. This invention addresses the non-linearity of amplifiers by forming a difference between the output signal and the unpredistorted input signal. Utilizing a complex LMS algorithm, the method adaptively corrects the amplifier's non-linearity before the quadrature modulator by adjusting the values of the complex quadrature components of the baseband signal.
