  • Patent number: 11757726
    Abstract: A hardware system for simulating a network physical layer for communication channels. The hardware system includes a plurality of hardware processors configurable to model a physical layer and communication channels. The hardware system includes a first interface coupled to the plurality of hardware processors. The first interface is configured to be coupled to a software simulator comprising a physics model configured to provide model parameters based on modeled communication hardware and a temporal modeling scenario. A second interface is coupled to the plurality of hardware processors. The second interface is configured to be coupled to simulated or real nodes for sending and receiving network data to and from the nodes. The hardware processors are configured to model effects of the physical layer and communication channels on the network data.

  • Patent number: 11677425
    Abstract: Systems and methods for evaluating link performance over a multitude of frequencies for Signal-to-Noise Ratio (SNR) optimization and mitigating interference. The methods comprise: communicating, from a first communication device, a first signal over a given channel in a given frequency band; receiving, by the first communication device, spectral power measurements and a Signal-to-Total Power Ratio (STPR) estimate determined based on a second signal including the first signal combined with at least one of noise and one or more interference signals (the STPR estimate accounts for the receiver performance including chip rate processing gain and/or the performance of an interference cancellation circuit used to remove the interference signals from the second signal); and determining, by the first communication device, a predicted Signal-to-Noise Ratio (SNR) condition for a plurality of frequencies within the given frequency band using the STPR estimate and the spectral power measurements.
