Title: Innovations by Alfonso Rodriguez-Herrera

Introduction

Alfonso Rodriguez-Herrera is a notable inventor based in Denton, Texas. He has made significant contributions to the field of telecommunications, holding a total of five patents. His work focuses on enhancing the performance and efficiency of testing methods in anechoic chambers and MIMO systems.

Latest Patents

One of his latest patents is titled "Positioning and weighting test probes in an anechoic chamber." This invention discloses an anechoic test chamber that includes six antenna probes, replacing a single probe with a small array. The array is used to form a beam that provides a similar signal to the probe signal, thereby reducing transmission loss. The alignment of the probes is meticulously designed in azimuth along four columns and in elevation along three rows, ensuring precise measurements within a specified degree of accuracy.

Another significant patent is the "Mobile-assisted phase calibration method and system." This method involves calibrating phase alignment of signals from multiple transmit antennas during over-the-air (OTA) testing of a MIMO device under test (DUT). The process includes generating a noisy test signal, transmitting it to the DUT, and analyzing the signal-to-noise ratio (SNR) to determine phase alignment. This innovative approach enhances the accuracy of OTA testing, which is crucial for modern telecommunications.
