Introduction

Nicholas Dean Walker is an accomplished inventor based in Kirkland, WA (US). He has made significant contributions to the field of technology, particularly in the area of satellite communication systems. His innovative work has led to the development of a patented system that enhances modem array fault tolerance.

Latest Patents

Nicholas holds a patent for a "System for modem array fault tolerance." This invention involves a gateway uplink to a satellite that utilizes cross-polarization interference cancellation (XPIC). The uplink operates on two frequencies, each employing XPIC, allowing data to be transferred through four avenues: two polarizations and two frequencies. The onboard satellite hardware detects signals and produces in-phase (I) and quadrature (Q) data for each frequency and polarization. The first IQ data is processed by a first pair of modems, while the second IQ data is handled by a second pair. Each modem pair processes the respective IQ data to implement XPIC, ensuring robust communication even during failures.
